In the IELTS Writing task 2 you will be required to write an essay. You will have 40 minutes to complete this task and you will have to write at least 250 words. The essay in the IELTS exam is usually a persuasive essay. In a persuasive essay you have to convince the reader of your viewpoint. In simple words you will have to give reasons for your opinion.

Sample IELTS Writing task 2 Topic:
Young people should not be given unemployment benefits. Agree or Disagree.
I am not saying that this topic is going to come on the IELTS exam, but if it does come up you will have to agree or disagree with this statement and provide reasons for choosing your viewpoint.
