IELTS measures your reading, writing, listening and speaking skills, and assesses your ability to communicate for work, study or life in an English-speaking country.
Remember that skimming and scanning are important exam skills. Skimming is the quickest way of finding out what a text, or part of a text is about, and once you know the general subject, it's easier to read for detail. Scanning is the most efficient way of locating the information you need to answer exam questions.
It's important to underline or highlight key words or phrases in the questions. This helps you to focus on the Information you need to find in the text.
