continously revising throughout the year -regardless of whether you have immediate assesment on this topic. The ideal way imo would be to complete practice exam questions on the topics you have completed throughout the year. It not only makes sure you still know the content well but also helps you with understanding the exam type questions and also timing.
Yep, agree with this.
It might seem silly at the time, or as though you have "more important" (read: closer) assessments to worry about, but just a bit of light revision here and there throughout the year will do wonders. Grab a random page of your notes, give them to a friend or family member, and get them to test you. If it's July and you're being tested on content from March, that's actually really great. If you struggle with it, work on it for 15 minutes and you'll feel much better about the whole thing. Come the end of the year, practically everything will still be relatively fresh in your mind. What this means is that you can focus on refining your answers/completing practice exams, instead of trying to re-teach yourself the entire course (as will be the case with some people - not ideal!).
Of course, there'll be times where you'll have heaps of SACs coming up and like, doing that^ just won't be feasible. But if you have a spare 10 or 15 minutes here and there, that's what I'd be doing in order to retain knowledge.
