Looks like you've covered everything but I have a couple of suggestions, mostly to do with readability. Images for stuff like the graphs would be great but also some emphasis on key points so you don't need to read through everything in the paragraph to find what you're looking for. Time management in the exams is very important and I'm concerned that (somewhat like what sine mentioned) navigating your reference (should you need it) will cost you more time than what's reasonable.
Something superfluous but possibly handy would be including degrees as well as radians in your trig notes. Obviously it's not that hand to remember, or work out, but degrees do occassionally show up in Methods and it does catch people out.
You can make some very neat and easy diagrams using Geogebra or something similar, if you're interested. Overall, it seems like you have a very strong grasp on the course.
