Revision resource suggestions
Revision is a very personal thing. There are a variety of strategies to try, but not every revision
strategy suits everyone. It is important to find something that works for you. Below is a list of
revision strategies and links that you might like to try. Remember, to be effective revision must
be active; so make sure you have something to show for your revision at the end of your session,
whether it is a mind map, a series of answers to questions or a mark out of for an online quiz.
