IELTS 18 gives students the perfect opportunity to familiarise themselves with IELTS and practise examination techniques using authentic test material. You can choose either an edition containing four complete tests for the Academic module or for the General Training module. An introduction to these different modules is included in each book, together with an explanation of the scoring system used by Cambridge University Press & Assessment, the producers of the IELTS test. The books come with answers and extra explanations, audio for the Listening tests, tape s, sample Writing answers and an example Speaking test video, so they are ideal for self-study.
