The first task in the Academic IELTS needn’t necessarily be a chart or a graph. It could also be a diagram. While preparing for the writing test, practice diagrams as well. If you are not well prepared beforehand, you will have to spend more time on this task. That means you will get less time to write your essay.Ideally you should spend 20 minutes on the report and 40 minutes on the essay.
The IELTS questions can repeat. Go through the question papers of the recent exams and familiarize yourself with the questions. Most of the questions in the Speaking test repeat. The questions in the Writing test can also repeat. Practice writing the essays asked during the recent examinations.
