Here is an activity where learners can practise 570 words that have been identified as important for the IELTS exam. You need to recognise them in the listening and reading sections and it is good to use them in the speaking and writing sections.
In this activity, you'll be tested on 10 words at a time and you'll have the chance to review the definitions after each set of ten.
