Three books of practice tests are available for the updated KET exam. Each contains four sets of exam papers from Cambridge ESOL. These past examination papers provide the most authentic exam preparation available. They allow candidates to familiarise themselves with the content and format of the examination and to practise useful examination techniques. These papers follow the March 2004 revised exam specifications. Student's Books come in both 'with answers' and 'without answers' editions. The Self-study Pack contains a comprehensive section of keys and recording scripts, making it suitable for self-study, and is accompanied by the Audio CD set.
