You will need a Jeppesen Student Airways Manual and copies of CAP 696/697 and 698; the latter are downloadable I believe.
A chart strip (several would be better!) - a piece of OHP transparency cut into a strip 12" long, half an inch wide with a straight line ruled on it for the length in a bright colour (red, blue, green).
When you come to use the CAP 696/7/8 books, they are useful when reading across the performance charts as you cannot leave any marks in these for the exams.
