  1. Hi Ms. Liz,
    Can I write a declination on instead of a decline of…
    Thanks in advance.

  2. Hello, teacher Liz. I’m Japanese male.
    I bumped into this magnificent IELTS website by chance and got tremendous amount of useful information about IELTS through your lessons. I can’t thank enough because there are still few reliable exam tips in my country.

    By the way, is there an expression like this below? For writing task 1 (line graph)

    The figure rose to a high of 40 grams in 2007.

    I confirmed there is an expression like ‘dropped/fell to a low of A’ . So I wondered if there was the very opposite expression and consulted dictionaries but couldn’t find out.
    I’d like to know if you were not busy. Thank you.

    • The sentence you gave is exactly right. The number fell to a low of / the number dropped to a low of // the number rose to a high of / the number rose to a peak of / the number reaches a peak of / the number peaked at – all fine.

  3. Thank you very much 🙂

  4. Thank you…for your crucial advice.

  5. Thank you….for your precious advice.

  6. Hi, Liz! Thank you very much for your teaching – it is precious for me! I just have one question. What is the difference between “some” and “few” mistakes in numbers? How it could be calculated?
    Thanks in advance.

    • Frequent = band 5, some = band 6 and few = band 7. It is about the frequency that they occur. There is no specific number.

  7. you are a very good teacher

  8. hi liz, I’d like to say thank you for your lessons they are really helpful, easy to comprehend and remember. I regain my confidence to pass the ielts whenever I watch your videos and study your lessons. thank u..

  9. hello mam..i am belong to non-english country and that’s the problem of understanding all meaning. i have technically good knowledge but due to English i nervous most of the time to think how to improve my English..

  10. hi liz
    my doubt is to use the word plateau,steep signifies increase trend or decrease.

  11. hı teacher, I m Emre really you are a perfect teacher and ı want to meet wıth you really ı need to help teacher can you help me beacuse ı wıll take an ıelts exam and ı want to take 6 score

  12. Hi Liz!

    My name is Karen. I just want to ask, if you will be the one to take the exam what will you do first, the task 1 or the task 2? Which one would you recommend?. Thanks!

    • Personally I would do task 1 first and then task 2. However, you must decide for yourself. The key is not which one to do first, the key is controlling the time you spend on each one. Task 1 = 20mins and task 2 = 40 mins. You must stick to that timing.

  13. Hello madam.! Please give me some tips and suggestions for reading …..

  14. Hi Liz,
    Can I use “plummeted dramatically”? Or plummeted alone? Is it redundant?

    Thanks ☺️

    • Don’t add “dramatically”. The word plummet means that the movement is strong and sharp so you don’t need adverbs.

  15. Currently, I am struggling with the reading section of IELTS. My writing and speaking g are not good so I am trying to get maximum marks in my reading and listening section. What should I do?

    • Hi Ms. Liz,
      First of all thanks for sharing your knowledge to everyone, this is such a great help to all of us ( IELTS takers).

      In academic writing task 1, in your first paragraph after you paraphrase the information( line graph, table, diagram, etc), I have noticed in your model answers, it is always followed with ‘ Overall’…

      My question is in writing task 1, do I need to write a summary as my last paragraph? Because, I didn’t see that in your model answers.


  16. If we want to describe a pie chart or bar diagrams
    We can describe like this

    ” the greatest 67 % dogs followed by cat , fish and rabbits 12 ,13 and 19 ”

    In above answer instead of ‘followed by ‘ what word we can use . because in the same sentence we can describe more data and iam preparing for pte in short time we need to discuss more data about it
    Instead of ” FOLLOWED BY “

    • There are serious grammar problems with this sentence. “the greatest proportion could be seen in dogs, which accounted for 67%, and was followed by cats, fish and rabbits ( 12%, 13% and 19% respectively).”

  17. No article in front of peak?
    I am really happy to find out this site. Thank you so much with all information put on here.

  18. satwinder kaur says:

    how can i minimize the gramatical mistakes in my speaking. plz mam suggest me and i have my exam on 22nd may 2016.

    • During your test, you can’t afford to focus on grammar. You should just speak naturally and focus on expanding answers. It takes a lot of time to make English more accurate – certainly more than one day.

  19. Hii liz,
    I have one question “13th January” is one word or two word?

  20. Rakesh soni says:

    How can I download your audio clips

  21. Hi Liz

    Thank you.

  29. Nikunj Patel says:

    Your lessons really helpfull…thanks a lot…
    please give me the exact format for all types of essay

  30. Hi Liz,

    In this model essay, you wrote zero as 0, I thought that any number below ten should be written as a word. I’m a bit confused here.
    Many thanks

    • Descriptive numbers below 10 are written as words. Data from the charts is always written as a number regardless of if it is under 10 or not.

  31. Can I use the word ‘intersect’ for two lines on a line graph that meet at the same point. For example, The number of students who study English and the number of students who study Spanish intersect at 50%.

    Thanks so much!

    • “intersect” actually means they meet and them part. In other words, the cross each other. “to converge” means that they meet and stay together. I can’t comment on a sentence without seeing the actual graph.
      All the best

  32. Moumita Ghosh says:

    Hi Liz,
    This site is full of knowledge and it is really Awsm. Could me please help in this that is For the task 1 it is always needed to write in simple past to present the data of the graphs? Can not we use perfect tense for the same.

    • The tense you use to writing your task 1 depends on the dates given, ie past dates, future dates or no dates (present tense).

  36. Hi Liz,
    Do you have any suggestions with my work below? I would really appreciate for your comment. Thank you so much.

    The line graph shows the amount of cases of X disease in Someland over a 9 years period, from 1983 to 1992.

    The number of cases began at 100 in 1983 and remained almost constant for two years until it steadily rose to 200 in 1987. Following the increase, a fall back of 50% was noted in 1988.

    However, it immediately recovered with a steep increase and reached its peak to 400 in 1989. A slight drawback of 50 cases was then noted on the next year and remained at 350 in 1991.

    Furthermore, it dramatically decreased to a low of zero in the year, 1992.

    Overall, a fluctuating trend was observed for X disease cases in Someland between 1983 to 1992. There was no case noted in 1992 as compared to 1989 where it marked its highest number of 400.

  37. If i write my own essays which are depend on task 1,Will you check them out? Thanks beforehand.

  38. Good day Liz. Please comment on my work. Any suggestions? THANK YOU SO MUCH 🙂

    The line graph shows information on the amount of X disease cases reported in Someland over a 9-year period, from 1983 to 1992.

    Overall, the number of X disease cases has fluctuated between 1983 and 1982. Surprisingly, there was no case found in 1992 as compared in 1989 where the most amount of X disease cases was noted.

    The amount of case started at 100 in 1983. From this time, the number remained almost steady for two years until it gradually increased to 200 in 1987. Markedly, the number of cases dropped by 50% in 1988.

    Furthermore, the amount of X disease cases in Someland significantly rose from 100 in 1988 to 400 in 1989, an increase of 300 cases to be exact. Following the increase, the figure started to decrease slowly until it experienced a huge drop by exactly 100% from 1991 to 1992. From a record of 350 cases in 1991 to zero case in 1992.

    • It’s good. Be careful with your grammar “the number of cases has fluctuated” should be past simple not a prefect tense. Also make sure you remember to write the “s” on “number of cases”. Otherwise, it’s good.

  39. Mahmud Salem says:

    Hi Liz .
    I was wandering whether it is correct to write in task1 words such as ( infer, deduce , extrapolate ) for example . Overall, it should be deduced from the pie chart that the proportion of female graduates grew exponentially over the period given. It can also be extrapolated that the most sought-after job amid female graduates was nursery.

    • It looks like vocabulary you have learned in order to get a higher score and isn’t at all natural for an IELTS report. I wouldn’t recommend trying that – the examiner knows all the tricks students try to get a score higher than their own level of English.

  40. Hello mam…
    I have been following your site since a long time as I am an ielts studentb so, am very keen to look forward your exam tips… It’s really helpful for those who are stick to a certain band score… Kindly shed a light on brief explanation on cue cards as well… That will be really great help from you…

  41. Can you please evaluate my writing?

    The chart demonstrate the amount of cases of a specific disease( disease x) over 9 years from 1983 to 1992 in someland.
    It is clear from the chart that the figure of cases was not remained steady. At the beginning of the period in 1983 the cases were 100 and in 1984 it stayed constant. then there was a slight increase on the cases from 1984 to 1987 and the level rose from 100 to 200. after that it dropped in 1988 and again it was reached in 100.
    On the other hand there was a dramatic rise from 1988 to 1989. 1989 was the peak year when the amount of cases was in highest number and it was 400. from 1990 to 1991 it maintained the same level of 350. But it is clear in 1992 there was a major drop on the number of cases and it fell from 350 to zero (0).

  42. Hi Liz ,i find out your webstites and videos more beneficial ,thanks for everything .I have a question .In line graph you have repeated more than twice ” the number of case of deases” in writing task1 samples.Can i use “the range of case of ilness” or ” the number of condition of ilness”?

    • It’s great to paraphrase but be careful. You don’t want to make more errors. You could write “The quantity of illnesses…” or “The quantity of cases…” but you can’t write “condition of illnesses”. The paraphrases for line graphs mainly comes from paraphrasing “increase” or “decrease” – basically, using a range of language which explains change over time.
      All the best

  43. Rajiv Rai says:

    Hi Liz , could you please review my writing as my exam is coming near and near and please let me know my weak points . As, I am hoping to score 7,8 . 🙂

    The graph illustrates the amount of cases of X disease in Someland in the span of 9 years (between 1983-1992 ) .

    Overall , it is clearly apparent that in the year 1989 there was a high number of X disease in given period . Whereas , the least number of this disease was in the last year 1992 . In the span of 9 years , there was only some few years that it was stable ( from 19983 – 19985 ) .

    With regards to the initial stage , X disease started with 100 in 1983 . This figure remained constant for some few years from 1983 to 1985 . Then , it increased significantly at 200 in 1987 before falling the same number as it was in beginning at 100 .

    However , in 1988 it skyrocketed at 400 and became the highest amount of cases of X disease of the give year . In the following year , it declined in 1990 and remained constant in 1991 with same numbers 350 . In the last year , the figure decreased significantly and hit the lowest point of 0 .

    • Hi,

      Unfortunately, I do not have time to give you comprehensive feedback Hopefully other students will pass comments to help you.
      All the best

  44. Can I use “stagnate” and “stagnation” as a substitution of “level out” and “leveling out”?

  45. Im so impressed with your lessons.thanks so much Liz
