i have my revision book, notes, and the little pages at the end of the salters student packs (which tell you what you should have in your notes/need to know) all in front of me... and make notes!
not the most interesting way to use, but ive just been writing summaries of my notes using these for each topic. it goes in a lot better, and i adjust the notes to my needs. (i.e. anything i find super easy, i just mention it, and go into a tad more info to bits im not sure on).
then i will go onto doing past papers. im leaving them for a little while until ive written my notes. i need to refresh my memory! and i find that writing notes is much more effective for me to revise. the stuff goes in this way!
