Becker, L. 2010. 14 days to exam success. Basingstoke: Palgrave Macmillan. An easy to read pocket guide
Cottrell, S. 2012. The exam skills handbook. 2nd ed. Basingstoke: Palgrave Macmillan. This has plenty of activities and scope for reflection
Evans, M. 2004. How to pass exams every time. Oxford: How To Books. A brief and an easy read, this book makes a useful introduction. Checklists at the end of each chapter, and highlight boxes emphasising key points. The last chapter on exam techniques on the day is particularly useful.
