Read and take notes. Once you have read all you need, condense the notes into brainstorms and revision cards. Create revision games. Do whatever works best for you. As for motivating yourself, revise somewhere with little to distract you where you will be most productive. This might be the library, school, wherever.
- Make a checklist of everything you need to kno.
- Summarise the entire exam if you can on one side of a4, but make sure you can expand on the pts.
- Do as many past papers as you can; questions only repeat themselves.
- And enjoy your revision, theres nothing worse than sitting down and hating what your learning.
