Just remember to date, title, and number every sheet of paper so that when it comes to organising loose bits of paper you don't mentally slap yourself like I did in yr 12. This is especially important once you start ripping bits of paper out of your book during revision.
I would recommend also focusing on organising your notes by exam. You can often fit two exams in a lever arch, hence you'd have 1 English folder split into two sections, exam A and exam B. Sub-spit each exam by section; poetry, plays, novels etc. placing your notes wherever they belong. Notes that cover broad themes etc. go at the very front of all of your notes in that section, i.e. the pastoral. This ties together all the subsections that come after.
Hope that makes sense.
