This book contains all the most important words that you need to know to successfully complete speaking and writing/essay parts of IELTS, TOEIC, and TOEFL tests. This material is perfect for any serious candidate who does not wish to waste time researching and learning new vocabulary the traditional way. This book will make your learning more efficient with less of your own effort, which means more spare time to review other concepts. We tried not to create just a regular dictionary with a bunch of words, but chose only the most necessary definitions from the official examination materials, and described them in the most accessible way.
