One of the best methods for revision I think is where you get a page in a text book/your notes book and you write it out taking out the unimportant parts. Then with this new page you just wrote, write it out again taking out more information. Keep going untill you get about a paragraph of solid knowledge. All the writing out helps you to memorise what you are reading.

Once that is done you have great revision material, break it up into sentences and use post-it notes and posters and things to drill it in.

Good luck in year 11 ;D
