Practice tests for the Use of English (C2 level) This edition of practice tests has been written to closely replicate the Cambridge exam experience, although it is also suitable for any English-language student working at CEFR C2 level. Each of its 200 exam-styled, single-sentence Key Word Transformation (Part 4) assessments carries a lexico-grammatical focus, testing lexis, grammar and vocabulary. Each assessment comprises a sentence followed by a 'key' word and an alternative sentence conveying the same meaning as the first but with a gap in the middle. Use the key word provided to complete the second sentence so that it has a similar meaning to the first sentence. You cannot change the keyword provided. Each correct answer is broken down into two marks.
