IELTS Diagram: Model Answer Band Score 9

Below is an IELTS diagram model answer which is estimated at band score 9. It is possible to have a diagram in your IELTS writing task 1 academic paper. A diagram is also known as a process. This is from IELTS Cambridge Book 8, Test 3.

The diagram below shows the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.

cement and concrete

Diagram Model Answer

The diagrams illustrate the way in which cement is made and how it is then used in the process of making concrete. Overall, limestone and clay pass through four stages before being bagged ready for use as cement which then accounts for 15% of the four materials used to produce concrete. While the process of making cement uses a number of tools, the production of concrete requires only a concrete mixer.

In the first stage of making cement, limestone and clay are crushed together to form a powder. This powder is then combined in a mixer before passing into a rotating heater which has constant heat applied at one end of the tube. The resulting mixture is ground in order to produce cement. The final product is afterwards put into bags ready to be used.

Regarding the second diagram, concrete consists of mainly gravel, which is small stones, and this makes up 50% of the ingredients. The other materials used are sand (25%), cement (15%) and water (10%). These are all poured into a concrete mixer which continually rotates to combine the materials and ultimately produces concrete.

Comments: This diagram gives a concise introduction. The overview contains key features of both diagrams and also highlights the connection between them. The body paragraphs are organised well and linking devices are used flexibly and accurately. Each body paragraphs explained the steps of each process in a logical order. Complex sentences are accurate and there is also passive voice used. Collocations are well used.

  1. Hello Ms. Liz
    Do we need to have almost 5 letters space at the beginning of each paragraph?
    here is an example:
    The diagram illustrate the way in which cement is made ………………………………………………………………………………………………………………… etc
    In the first stage of making cement ……. etc

  2. Hi Liz,
    Dont you need to compare two processes in body paragraphs?

  3. Good day Liz!

    I would like to verify if an overvkew is needed for a process chart? Thanks and God bless.

  4. I write overview after introduction in task 1 but i begin my sentence with word overall in last paragraph. will it decrease my overall score ?

    • If you have confused the examiner with indicating two overviews – for example, having an overview after the introduction but also using the word “overall” at the end of your report – your score will be reduced for Task Achievement, which is 25% of your marks.

      • overall score will be reduced by 25% or in Task Achievement only ? I’ll be glad if you make me clear about it 🙂

      • It might also affect your score for Coherence and Cohesion as you have separated the overview into two paragraphs instead of collecting it into one paragraph.

  5. My introduction for this diagram. “This diagram illustrates the different phases and tools that are required in the procedure for manufacturing cement and then how this is mixed with other materials to produce a mixture used for constructing means/aims.”

  6. Hi Liz,
    I really like your website! I’ve been using it a lot! Thank you so much for the help. I think this is the best tips I have taken from the Internet. I’m practicing for the IELTS but I never finish on time this first task. Could you tell me what is the best strategy to manage time? If I dont finish the writing, will I get a low score?

    i just want to ask that is conclusion is necessary in map and picture graph..

  8. Cherbt Necaerde says:

    Dear Liz,

    First of all, thank you so much for creating this website.
    It is so helpful!

    Do you mind taking a look at my version of this exercise?
    Thank you in advance 🙂
    The present diagram depicts the various consecutive stages required to make cement, as well as it illustrates how to create concrete out of it.

    To begin with, to produce cement limestone and clay are both crushed in order to receive a powder, that consists out of these two sources. After that, the powder passes through a mixer and following this, it is heated while being rotated. In the next stage, our intermediate product is ground, so we eventually get cement. After all of this, the cement is packed in small bags, so it’s ready to be dispatched to the markets.

    In terms of creating concrete, one has to obtain multiple resources to pour into a huge blender, called a concrete mixer. It is quite obvious that the cement will be needed, but it will only contribute for a small 15%. Apart from this, it is apparent from the image shown that we also need some water, which will make up one-tenth of the total amount of concrete. Furthermore, it is also revealed that sand and so-called gravel, a type of stones, are crucial. They contribute respectively for a quarter and half of the total mixture.

  9. Hey i just love ur videos..Kindly tell me whether we have to write conclusion in task 1??

  10. shajahan masum says:

    hi liz,
    please give some synonyms for the word Fluctuation which I use it for more ups and downs in list or chart..

    • You can use fluctuation or fluctuate. There is no synonym which is better. Just alternative verb and noun. Also you should not be highlighting more than two fluctuations anyway.

  11. hi mam
    could you plz help me with a doubt.if i write THE DIAGRAM ILLUSTRATES..instead of illustate… is it wrong..

  12. could u please add model answer for comparison diagrams…

  13. Hi Liz Madame,
    I have just finished my IELTS exam at the British Council in Oman yesterday. in writing Task.1 I got two diagrams, of which one represented the layout of Bern Hill Farm in 1976 and the second was the transformed layout of the farm to Bern Hill Environmental centre in 2006 (the question was to report the relevant features and compare)
    task 2 was about Agree/disagree topic on “some people think that competitive sports should be banned for fear of the failure”
    I performed fairly in the speaking , reading and listening..but I couldn’t manage within the time limit because the topic was very interesting and my mind full of focal points.
    I was blessed with ur lessons and practice by which I could perform at least in this condition.I may need ur advanced lessons on writing, surely will b in touch

  14. Thank you Liz. I can see some of the mistakes I made in my first IELTS. This is very helpful.

  15. Harminder singh says:


    May i know in which tense we need to write our writing task 1- past or present..??

  16. Hi Liz,

    Thank you for your wonderful work on IELTS lessons. It is clear and so much easier to follow compare to other sites.
    Is it ok to write both introduction and overview in one paragraph ?


  17. kimloing says:

    The provided picture illustrates about the process of creating the cement and the steps of making concrete for building purpose.In general, the cement is made from the limestone which is the main substances of the process and also for the concrete production.

    Based on the diagram, it usually takes 5 steps to make cement. First of all, limestone is mixed with the clay. Both substances are flow by a tube into the crusher to brake it into small particles. Next, these petite particles are going to be homogeneous by using the mixer then it is passage by the same tube and go across the rotating heater which uses the temperature to burn the enormous of both ingredients. Finally, put those substances into grinder and packaging it.

    To product the concrete, people should take 15% of the cement to mix with 10% of water and also with the 25% of sand then put the 50% of small stones into the concrete mixer. Finally we can get the liquid for build the building.

  18. Hello Liz
    Please here is my task 1 writing, i hope you please go through it and see if i can score band 9.
    The diagram illustrate the methods taken for cement to be made, and process involved to produce a concrete.
    Overall, limestone and clay are the raw material that are used after going through a series of four process to form cement, the cement account 15% of required material used to form concrete. while concrete is made by combining four material in a specific percentage in a mixer.
    in the first diagram, limestone and clay are crushed to a powder form, and then convey then convey to a mixer where the two component are properly mixed, the mixture are forwarded to a rotating heater which heats the mixtures at a constant temperature at the end of the tube, the mixture proceed to the fourth stage of crushing the mixture where finally ,cement is manufactured. The end stage which is bagged the cement and ready for use.
    in the second stage, concrete is manufacturer by the combination of four building material which are mixed in a specific percentage. the materials are cement 15%, sand 25%, gravels 50%, and water 10%, all this material are poured in a concrete mixer. the component are properly mixed until a concrete is made.

  19. YASIN SHEHU says:

    Dear Liz
    The diagram illustrate the steps taken to produce a cement and how it is then used to made concrete. overall, limestone and clay are the raw material obtained which are sets to passes through a four consecutive stages before a cement is produced, while concrete is formed by the percentage of four material and cement is 15% contains.
    from the first diagram, limestone and clay are crushed together to formed a powder where is they are being combine in the mixer before heating at a constant temperature they are moved to a grinding stage and finally to the final stage which is package ready for use.
    considering the second diagram, concrete are form by mixing four component namely Cement, water, sand gravels which are small particles of stone.they are all poured in to a mixer which continously rotated.

  20. in academic writing task1 do we have to write overview as a new paragraph or write it into introduction paragraph?

  21. Hi Liz
    I’m fully aware of that there is no conclusion in task 1 but overview.
    But, interestingly, I came across some of the IELTS books’ sample answers where they gave conclusion, such as IELTS practice test plus 2 test 4.
    Would you please explain me at your convenient time possible?
    Thanks a lot for your wonderful assistance you are providing for free…

  22. Hi Liz,
    First of all I want to thank you for your all useful informations.

    My question is what does it mean ‘account for’?

    I really could’t understand the exact meaning of it, although I have looked up in the dictionaries and knew the meanning.


  23. Wouldn’t it be better to write 4 paragraphs (intruduction, overall information and 2 body paragraphs)?
    Sometimes I can see conclusion at the end of the sample task 1 which doesn’t give information but is quote kind of sentence. Is it needed?

  24. HI liz thanx for ur great support. I want to know that what should we use in LRW test pencil or pen?

  25. Hello Liz,

    First of all, i would like to big thank you for a very useful and wonderful your site☺

    I have two quiries .
    (1) you had used so many times the word like”spent” in writing task 1. So if we use a one word more than once in writing task 1,Would it chance to loose band?
    (2)In which situations, Will we use passive voice in both writing tasks?

    Best Regards,

  26. Dear liz for the diagram of cement and concrete production my introduction and overview is : the diagram below illustrates the steps and materials employed for cement production and how it is used for manufacturing concrere. Overall production of cement is a multi step process which begins with the mixing of lomestone and clay and endes with grinding of the resulting product while concrete is produced in a single step. What is the expected band score i can get for this

  27. Is it allowed to use caret /\ for inserting words or sentences ?

    • I wouldn’t insert a sentence because it might be difficult for the examiner to read. But inserting a word or two is fine. Just make sure everything is very clear and easy to read.

  28. Hi Liz!
    In writing, is it alright if I have many erasures? Using pencil, every time I will erase some words this will create a blank space between other words. Which makes my paragraph untidy. Will it reduce any points on this?

    Can I have tips to make my writing presentable?

    • If the examiner can read it, it’s fine. If you need to erase something, make sure it is fully erased and the new word is easily seen.

  29. Hi,
    I wish to clarify whether it is necessary to write the overall idea in the introduction paragraph. My coaching class taught me to write it at the end. Please do reply

  30. Thank you, you’re the best!

  31. cta sapkota says:

    Hello ma’am,
    First,I want to thank for your effort in helping us.
    I have test coming up at the end of this week.I am not sure about what to write with in writing task,pencil or pen!Which will you recommend? I apologise for asking irrelevant question here.

    Thank you

  32. Dear Liz,,
    First of all I would like to say a big thank you for your great job 🙂
    You said that we should write overview in writing task 1.but if we have a diagram,what kind of overview should I write in that case??.
    Thank you..

    • The overview contains the key features which are often main stages (but not always when you see the water supply diagram).
      All the best

  33. Dear Liz,

    First I’d like to thank you for sharing this amazing website with us. You have been doing a wonderful job!!!
    Second I’d like to ask you about the overall paragraph. Is it possible to write the overall at the end of task 1. I mean, in this example I’d write in the following order:
    1. Introduction
    2. Cement diagram
    3. Concrete diagram
    4. Overall

    Would it be ok?

    Thanks in advance.

  38. Hi mam, can I use your model answer to write in my writing, I mean can I memorise the structure answer of each question types to do my report. Will the examiner realize that and will it affect my score ? Thank you 🙂

  39. ielts7que says:

    Hi would you mind giving a look to my answer.
    I know it is not correct but I find it difficult to write 150 words, since I can’t count point or commas.
    Here’s my answer:
    The figures depict the process of how to produce cement and concrete.
    The process begins with limestone and clay and culminates in concrete.

    To begin, limestone and clay are crushed and become powder.
    Subsequent to that, the powder produced is mixed before being rotated and heated at the same time.
    Once this stage is completed, the mixture is place onto a roll before passing through a grinder to make cement.
    Then, the producted cement is packed into bags.

    Afterwards, in order to produce concrete, a concrete mixer is utilized.
    The mix is placed into the mixer consists of 15% cement, 10% water, a quarter by sand and a half by gravel (small stones).
    Lastly, the concrete mixer make all the materials rotate,this way concrete is created.

    Overall, the entire process can be divided into two main phases: the first one results in the cement production,followed by the second one which ends with concrete.

    Do you think I can get at least a 6.5?

  40. Hi guys i have my ielts exam tomorrow .

    I had appeared twice bt could not get the required bands of 7 EACH.

    Hope i can make it happen this time.

    Fingers Crossed :))

  41. dear Liz,
    i really appreciate you valuable lessons. if it is permitted, i would like to ask about overview and introduction ,because what i have written is a bit different from yours.

    While the first diagram illustrates how to make cement, the second diagram shows how to produce concrete using cement for building purpose.

    Overall, the cement making process uses two ingredients (limestone and clay) and five different equipment (crusher, mixer, rotating heater, source of heat and grinder), while the concrete production uses four different ingredients (cement, water, sand and gravel) and only one equipment which is concrete mixer.
    And then body paragraph…

    1-is it appropriate to use ”the first diagram …..the second diagram….”?
    2-is it fine to use ” while” in introduction and in overview again or too much repetition? ( i need band score 7.5).
    3-here ingredient(s) is countable, and equipment is uncountable, is that right?
    4-is there too much detail in overview or still ok?
    much appreciated your help, thank you.

    • Question 1) Yes, it’s fine. Question 2) You should try to avoid repeating linkers, so use “whereas” for the second option. Question 3) “ingredients” is only for food, you need to use “materials” and equipment is uncountable. Question 4) avoid writing lists in the overall – you have tried to list all equipment instead of summarising the key stages.
      All the best

    • thank you so much!, you have been very helpful.

  42. Dear Liz,

    Can you explain for me how to you the word “the” correctly in this task? For example, the last sentence of the first paragraph, why the word “cement” is mentioned for the second time, it still stands alone?

    Thank you,

    • Because they are two different nouns. One noun is “concrete” and the other noun is “concrete mixer” which is a compound noun.
      All the best

  43. Dear Liz
    hello , i got a question
    dose flow charts come also in task 1 for the academic exam ?


  44. Writing task-1 is important in band calculation or not important? Mem, please give the knowledge about writing task band calculation with examples and also give the knowledge about weightage of each task(1,2)

  45. Mozhgan says:

    Hi dear Liz
    and than you a lot for your great sample answer!
    I have a question. at the end of your essay, you wrote — ultimately produce concert.
    did you mean produces? or I’m wrong?
    By the way you are wonderful 🙂
    with the best regards

  46. Haneen Alhroub says:

    Dear Liz,
    Can you check my writing please and give me any additional tips (:

    This diagram illustrates a series of steps and different instruments for cement production, which in turn used in concrete manufacturing for construction uses. Overall, five main upstream processes needed for cement manufacturing that including (crushing, blending, heating, milling and packaging), while only one downstream process achieved in concrete production.

    In term of cement production, limestone and clay were crushed together to form more fine particles. After that, the resulting powders were mixed well to ensure adequate particles distribution. The rotating heater melts the mixture which then mill through the grinder equipment to obtain a homogeneous cement particles. A packaging step takes a place as a last process.

    However, in concrete production an uni-step is achieved unlike the cement manufacturing, which is a multiple steps. But at the end, these two types of production still complement each other. In the concrete mixture, 15% cement, 25%sand, 50% gravel with a little of water were added and blended together by circular movement to form concrete as a final product ready to use.

  47. Hello, Liz. Here is my task 1 article for this diagram. Hope it would be a bother to check it and give advice since I really did bad in IELTS writing part (6.5) several months ago. Thanks a lot.

    The diagrams illustrate the process of producing cement with detailed procedures and relevant equipment as well as the production of concrete.

    Overall, limestone and clay are fundamental ingredients manufacturing cement by 5 essential steps, while concrete is made from 4 categories of raw materials, namely cement, sand, gravel and water.

    In the first diagram, the crusher make limestone and clay into powder to be prepared for the mixing procedure by a mixer. The powder that is well mixed is delivered in a continuous rotating heater, which is heated constantly. After that, high temperature powder is sent to grinding section where the production of cement is completed. Finally, settled quality of cement is packed in bags and ready for concrete production.

    In the second diagram, four different sorts of ingredients, which are 15% of cement, 25% of sand, 10% of water and 50% of gravel (small stones), are loaded in a concrete mixer that is spinning to blend all the materials and output concrete eventually.


  48. Emmanuel says:

    Hello Liz,can the introduction and the ooverview be merged in one paragraph?

    • Both statements can be put into one paragraph but they must still be separate sentences and easily distinguished from each other.
      All the best

  49. Lemuelle Bryan says:

    The diagrams illustrate the steps and tools used in the cement-making process and cement used to yield concrete for building purposes.

    The production of cement has 5 stages, it commence with the mixing of two raw materials and completing in the packaging a new cement.

    Concrete production has a simpler process by mixing the four elements (Cement, water, sand and gravel) in the concrete mixer.

    It starts with Limestone and clay is crushed together, resulting in powder is then mixed. Once Limestone and clay are collected as one, it passed through a rotating heater to heat. After being heated, travels over a conveyer belt to pound through a grinder. At this time, cement is produced and it is packed in a bag and delivered to the building site for concrete production.

    Concrete production begins, mixing the 4 elements, Cement (15%), Water (10%), Sand (25%) and Gravel (50%) into the concrete mixer until it is ready to use.

    • You will need to work on how to write an introduction (only one sentence for both diagrams) and then how to write an overview (all key features for both diagrams). Please see my models to learn more. Also be very careful with using capital letters – you have quite a lot of mistakes in this writing.
      All the best

  50. Dear Liz
    I like your blog so mush,and this is the first time I write here.I hope you can see my essay that I have written before seeing your answer,and give me your opinion.

    This diagram illustrates the different stages in producing cement and how it is used with other substances to make concrete.Overall,cement,one of the four basic components of concrete,is not found naturally, but there are four phases to produce it.

    To manufacture cement ,we need two materials : limestone and clay ,which are crushed by a specific machine into a powder. The next stage is mixing these components together by a mixer before going into a rotating heater .In the third stage,the rotating heater allows the mixture to move around, so that the heat distributes through it. Finally, a grinder is used to crush the mixture into a fine powder ,which is bagged later to use as cement.

    To produce concrete ,we need only one stage and four components with different percentages (15% of cement ,10%of water,25% of sand,50% of gravel).All these substances are mixed together by a concrete mixer to make the concrete .

    Thank you

    • The main issue is on the overview. The overview must contain the key features of both diagrams and is the most important statement in the whole report. Without a very good overview, you will not get a good score in task achievement which is 25% of your marks. Spend time working on improving your overview. Also try to avoid using “we” in your report.
      All the best

  51. Dear Liz , here is my task 1 writing for this diagram . Would you don’t mind please check my writing and give your opinion which marks I deserve .

    The diagrams provides the visual information of about the process of cement production and how it is used in concrete production .
    Overall the whole process of cement production is experienced five steps then cement is used in concrete production which is followed few steps for building purpose.
    With regards in cement production ,it can be seen that lot of tools are used with various ingredients . Lime stone and clay are main items which are crushed to form powder through crusher . After that the powder combined into a mixer and passing through a rotating heater which has heat applied. Then the powder transformed into a cement by grinder .The last step is the final product which is put into bag.
    The second diagrams represents that four materials such as cement , water, sand & gravel which is known as small stone with 15%,10%,25% ,50% respectively . Among all of these ingredients gravel are used in highest proportion . These are all poured into a concrete mixer . This mixer combine the all materials and the final product is concrete .
    Best regards

    • Hi Sony,

      You have the right information and have organised your writing well. The overview could have been more fully written. However, this is probably around band 6 due to frequent grammar errors. You need to check the use of the passive voice and also review when and how to use articles (a / the ) and plurals. Here’s an example: “Lime stone and clay are main items which are crushed to form powder through crusher” = Lime stone and clay are the main ingredients which are crushed to for a powder in a crusher” – that’s 3 errors in this sentence with also issues about vocabulary.
      All the best

  52. Hi Liz,
    The collocation you mentioned in the diagram easy is elusive to me.I tried checking it up but cannot make meaning out of it.Can kindly explain it .

    • Hi Magnus,

      What do you mean? Do you mean the comment that collocations are well used. Collocations simply refer to putting the right words together. For diagrams, this is particularly important because you are often given the nouns in the diagram but you must choose which verbs to use with them. This model uses the right collocations – the right verbs with the nouns.
      All the best

  53. hi liz, you once said digits less than 10 should not be written in words in one of the comments replied to, in one of your exercises. why have you written four in your model answer ?

    • Hi,

      The comment was written here on this page: This relates to whether the numbers are statistics given in the chart or whether they are used descriptively to describe the number of categories. If the numbers are only descriptive (which relate mostly to introductions), then numbers under 10 should be written as words.
      All the best

  54. dear Liz,I hope to have a look in my answer, The diagram illustrates how cement is produced step by step and the used equipment,and the process of concrete production from cement to be used in building. To sum up,the data clearly shows 5 main stages for cement production starting with limestone and clay with the help of several tools.Also,the use of certain amount of this cement (15%)together with other ingredients to produce concrete. When we have a look to the first diagram,we can see that,firstly,limestone and clay are put together to be converted into a powder form using crusher.The powder is then mixed in amixer and passes through a rotating heater supplied by a fixed heat system.The resultant mixed and heated powder passes over a grinder to yield the cement which is then packaged into large bags. The process of concrete production begins with adding approximately 15%of cement and 10%of water to25% sand and50% small stones(known as gravel).They all are mixed together in large concrete mixer to produce the concrete.

    • Hi Dina,

      You’ve got the right information and it is in a logical order (You haven’t made your paragraphing clear but I guess that was just an oversight). If you used paragraphs correctly, it would probably get about 6.5. Here are some comments to help you improve:

      1. In the introduction, make sure you write correctly if there are diagrams (s) or diagram (only one).
      2. Try to avoid using “we can see” – don’t use “we”. You can change it to “It can be seen…”
      3. remember your articles (a crusher)

      All the best

  55. is it advisable to put the summary of the overall process or feature in a task one essay immediately after the introduction or at the end of the essay? the idp material i came across lately, advised that it should be at the end of the task. please advise me liz

    • Hi,

      There is no right or wrong for this. The examiner is mainly concerned that the overview has all the key features collected together and is put in a logical place. There is nothing in the marking which states it must be at the end. So, it could be after the introduction or at the end of the report. I often prefer to put it after the introduction so the reader can read the key features before the smaller details which is actually more logical. However, putting it at the end of the report is perfectly good.

      For diagrams, however, because the introduction is often short, I tend to put my overview in the same paragraph – starting it with the linker “Overall,..” helps the examiner locate it quickly and easily. So, there are a couple of options of where to put it.
      All the best

  56. Dear Liz,

    Here is my task 1 writing for this diagram. Hope you wouldn’t mind to have a look and give your valuable opinion.

    The given diagram depicts the different steps and equipments used for the process of cement production, and the method of using this cement to produce concrete for construction purposes.

    Overall, the whole process of cement production includes five different steps and a number of instruments. This cement is later on used to make concrete along with water, sand and gravel(small stones) in certain proportion.

    To begin with, limestone and clay are crushed together by a crusher to obtain their powder form. This powder is then passed to a mixer. From the mixer it moves to the rotating heater, where the mixer is processed by heating. Heating is followed by the process of grinding. A grinder is used to produce the smooth cement which is then ready to be packaged and sold.

    Regarding the second diagram, the concrete used for various building purposes is produced by mixing gravels(50%) with 15% cement, 10% water and 25% sand. All those items are mixed together in a concrete mixer in the measured proportion to get the perfect concrete for building purposes.

    (***It should be mentioned that, I wrote it before reading the model answer and tried to follow your previous instructions) Thank you in advance.

    Best wishes,

    • Hi Mou,

      It’s very good. It’s borderline 8. Your task achievement and coherence and cohesion are both very strong. There are a few minor errors in grammar and vocabulary:

      1. In the overview “later on” should be written as just “later” for academic writing.
      2. “here the mixer is processed by heating” = the mixture is processed – it is the mixture not the equipment which is processed.
      3. gravel is uncountable
      4. to write the percentages, you should write 15% of water, 25% of sand – it’s more grammatically correct.
      5. “the measured proportion = proportions (you need plural here)
      These are minor errors – it’s still a very good report. Well done!

      • Hi Liz,

        Thank you very much ! I’m feeling more confident now and will definitely follow your advice. 🙂

        Best regards,

  57. Dear Liz,

    Isn’t it a typo in paragraph two, in the middle of line three – ‘… which has constant heated applied …’?
    Did you mean ‘heat’?
    As for the description itself, it is very useful as I, for one, find this type of Task 1 a little problematic.
    Thanks lot..

    • Thanks Sergei – much appreciated. Sometimes I can’t spot my own typos 🙂 Diagrams can be remarkably simple to write as long as you follow a logical order and describe each stage clearly. Also take a look at the use of linking devices – next, then, following that, afterwards etc – diagrams have specific linking devices which you can use.
      All the best

  58. Dear liz,
    Dont we have to write a conclusion for flow chart/ pictograms?? or can we avoid that if we present the gist of it in the introduction itself?
    many thanks liz for supporting us like this.

    • Hi,

      You need to watch my collection of free videos on writing task 1: These lessons will explain what the examiner is looking for in task 1 which is basically an overview not a conclusion. You will see in the model that there is a clear overview. If you look at the other model task 1, you will see the overview is actually presented as a separate paragraph.
      All the best
