Success in the IELTS exam requires two things. The first is understanding the test and building up skills strategies for different types of questions. The other key is to build the language that is needed to be successful. A wide range of vocabulary is needed in order to be able to impress the examiner in the speaking and writing test. A wide range of lexical resource (vocabulary) is also needed in order to be able to understand what you hear in the listening test and what you read in the reading test. Although there is a plethora (huge range) of books on English vocabulary and even on vocabulary for the IELTS test, in my opinion the best book is the one published by Cambridge.
The main reason why I like this particular book the best is for the following reasons:
- It focuses on the frequent topics and a speaking and writing test such as: health, education, technology, media, and crime.
- It uses IELTS style tasks to help you learn vocabulary. This means that you are actually killing two birds with one stone (getting to results from one piece of effort). You get to learn new words and you also get to practice IELTS listening and reading tasks, and also do tasks that help you prepare for the writing and speaking tests.
