IELTS Writing Academic Task-1 Line graph: Important Tips

#1 Choose the actual key features:

When you analyse the line graph always remember that ‘key features’ does not mean just any random information from the visual data. It means that you have to study and interpret the main trends that the line graph is showing.

So, take your time to understand the line graph thoroughly.

#2 ‘Overview’ paragraph is a MUST:

Write a short overview of the main information you identified in the line graph. Candidates often overlook this step and loose band scores as a result.

It is very important to give one-sentence overview of the main trends in the line graph. You will not achieve a good ‘Task Achievement’ score if you miss out on this.

#3 Make use of synonyms:

Synonyms are a great tool to write the same information presented in the question statement but differently.

Therefore, whenever you think of good synonyms for the words in the statement, apply them, it will show the examiner that you have good a range of vocabulary.

#4 No need to write specific numbers:

IELTS is a clever test especially in line graphs, where it becomes hard to figure out what the exact numbers are.

In such conditions, it is better to use the words such as – approximately, nearly, just above or just under; rather than writing specifics. It also demonstrate your English analytical skills.

#5 Follow the 5-step structure:

Always make sure that your line graph description is logically structured. If you do not adhere to this, it can be very hard for the examiner to gain a clear perception of what you have described.

For your ease, I recommend using and practising writing with the help of 5-step line graph structure explained above. If you practice this enough, it will be ingrained into your brain, and you won’t miss out any important steps during the exam.
