A good technique for the IELTS reading test is to do easy questions first. If you get stuck on difficult questions, miss them. Do the easy questions, then return to the tricky questions later.
What's the easiest type of question?
The easiest type of question is probably any question that contains a name, number or date. For these questions, it should be easy to scan the text to find where the answer is.
If you find it difficult to get started in the exam, look for a question with a name, number or date, and start there. An easy question will help you to start confidently.
