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。 This resource contains 200 exam-styled， single-sentence assessments， each carrying a lexical/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。 Next to each sentence transformation answer is a guide indicating the focus of the two parts of the either G （grammatical） or L （lexical）。 This device gives a rough indication to help you with your revision for the exam。 Jane Turner is an associate lecturer in EAP/EFL at Anglia Ruskin University， Cambridge， and an EFL materials writer for international exam boards， universities and publishers。 She previously worked as a Cambridge ESOL examiner for the British Council， and holds an MA in Education Management and Cambridge CELTA and DELTA。
