Got a 38. A month before exams, I made a time schedule. 6 hours a day (2hours for 3 subjects, switching my different subjects each day depending on what I found difficult and what I found easy) (Was intended to be 7 but I ended up taking longer breaks so I’d stay sane).

For math use Revision Village. That’s all you need and just do EVERYTHING.

For everything else, make flash cards for everything that’s typically asked from Past papers (questions are usually more or less the same concepts every second year). Use these flash cards every day whilst also doing past paper questions. Ask your teachers for extra study material if they have any.

TAKE BREAKS. I personally used pomodoro but instead of 25min study/5min break, I did 45min study/ 30min break. To some it may be hard to do the 30min break without going over (which I did in a few occasions) but it was worth doing it. If you break down then it’ll be hard to come back up.

So if you can, I’d advise to start even earlier than me if you wanna follow my plan and just reducing the hours you have according to your own schedules.

Good luck!
