IELTS Writing Test lasts for 60 minutes, and you will need to complete two writing tasks, each of which requires different text types (description, report, discussion, argument, opinion text).
IELTS Writing Task 1
In the first part, you are given a task based on some graphic or pictorial information. You are expected to write a descriptive report of at least 150 words on the information provided.
IELTS Writing Task 2
The second task is more demanding. You are expected to produce a written argument on a given topic and to organise your answer clearly, given some examples to support your points. You will have to write at least 250 words and, as Task 2 is longer than Task 1, you are advised to spend approximately 40 minutes on this task and 20 minutes on the first task.
IELTS General Writing
If you are planning to take the GT module, the Writing test is different. You are allowed one hour to complete two tasks, of 150 and 250 words, as in the Academic module. However, Task 1 is always a letter, while Task 2 is an essay based on a given topic.
