At this late stage in your revision schedule, you should not be revising from any textbooks or revision guides. Instead, past papers should be at the forefront of your revision. Complete as many past papers as possible, especially the most recent ones (June 2012 and onwards) as they will look almost identical to the ones you’re about to take.
Use your revision guides and textbooks as a reference point in case you need to read up on extra material but even so, try to avoid referring to heaps of information. This is because you have a number of exams in quick succession. Mark schemes and cheat sheets/notes pages usually work best. Cheat sheets are only a few pages long that contain the most important concepts/formulas of the syllabus.
When you complete those past papers, what you’ll notice is that you’ll have weaker and stronger areas. You should obviously dedicate more time to your weaknesses. Target these areas by answering a few more exam questions on these topics. This is how you’ll bump up your final grades from D’s and C’s to B’s and A’s.
If you feel you don’t have any good summary notes or cannot find any exam questions by topic, don’t worry. Over the last year or so, I’ve been compiling my own notes and resources for students I teach on a one-to-one basis. It’s taken me a long time to put together but I wanted to make sure you had all the best resources at your disposal. Here they are below. I would advise that you go through all of them and pick the ones that are most useful to you.
