Whatever you do, don't just copy/photocopy your textbook. This wouldn't be all that effective because sure, you're learning the material but it's from someone else's view, not yours. So make sure you look at a variety of textbooks or summary books if they're available so you can get a range of views on the coursework and summarise it in your own words. I cannot stress that enough.
Another tip would be to include examples and/or calculator steps for some of the more difficult questions, just in case you get stuck.
Although in theory this is a very good approach of making notes, you have to consider the fact that there's not really that much time left to start making notes from scratch. In order to fully benefit from the bound reference, the notes should have been written CONSISTENTLY throughout the year. However, because there is now a month and a bit until your exams, i think the best way of doing prepping the bound reference is:
a) looking through commercial notes in other books - A+ Further Notes (which are pretty good), textbook summaries, Itute, notes from class - and deciding which ones explain it the best and most concisely. What you're aiming for is a REFERNCE book, not a book to re-learn the whole concept within the duration of a 1.5 hour exam. So, good, concise notes/summaries.
b) If you come across notes with hard concepts, chuck in a few examples you've done before. This should be happening as you do prac exams. But you don't need examples for every concept. For example, if you confidently know how to find the IQR of a boxplot, just write down the rule but don't worry about drawing up 50+ boxplots as an example.
c) Do prac exams. Use your notebook when you need to. This year's further class at our school has a "star chart" for how many prac exams they've worked through. Sounds kiddish, but you will not believe how motivating it is get a golden star for every exam you've done. It's passive bragging - everyone asks: "Who's that person who's done 20 exams already?!" We have one for spesh too.

d) As you work through the prac exams and use your notebook consistently, you'll realise that there are areas in the notes that you can expand on, or condense, in order to access the relevant info quickly and accurately. So prac exams are a must.
