Your teacher has probably already given you a heaping pile of notes, but they might be too intimidating to go through.

You can start small and make the notes work better for you by creating your own notes from them. This especially applies to remembering Math formulae, as because even though the Math exam gives you a formula sheet, many of the formulas you will need for the exam are actually not on it.

Another perk of this is having a quick reference to look at, just before you enter the exam room. After all, formulas play a really important part in being able to solve questions.
