Revise with Post-Its

A painless way to revise key facts is to stick 'post its' around your room/wall/ceiling with the facts on. You can read them at various times of the day and it's amazing how often you will look at them over a weekend. Like the flashcard idea, you could write a question on one side of the 'post it' with the answer hidden on the back. If you keep looking at that question and not knowing the answer, it will annoy you to have to keep finding it out. Eventually you won't have to look any more. Make sure you keep changing the post-its once you know them.

Every day put a few up post its on your wall and take down the ones where you now know the information.
