motivate yourself- it's all about your mentality. don't always be making revision notes, though it's a bit of a concern if you haven't started yet. do plenty of practice questions with and without your notes to help yourself consolidate the content. break it down into manageable chunks, but if you haven't even started, then be prepared to put a lot of work in. condense key facts into flashcards as an easy revision tool. getrevising has past papers you can do if you want to nail your exam technique.
a timetable can provide a good guide, but don't be upset if you don't follow it everyday, but definitely have some sort of schedule of what you'll be revising each day.
good luck!
