I’m almost through year 12 and I’ve just been winging it the whole time, to be honest. I can tell you about my organisation though:
First, buy a metric ton of paper before you start or along the way, because you will have to scribble down about 10 trees worth of content.
ALWAYS write the date on your notes/handouts because you will forget when you wrote them and which topic they belong to haha.
I take a smaller ringbinder folder to college with me, which just has work in it from the last couple of weeks. That way I don’t break my back lugging 3 giant folders back and forth and I have (most of) the things I need to hand.
Everything else goes in to bigger lever arch folders which stay at home. Divide up different topics using post it notes or cardboard dividers. Often the simplest systems work- you don’t have to overthink it or colour code everything.
Apps are great for organisation- My Study Life gives you a notification just before a class is about to start, which is great if you have weird gaps in your timetable as you don’t constantly have to check when your next lesson is.
Also, you can track your revision progress using Adapt, which gives you a checklist of everything on your specification. It also suggests topics to revise on that day.
I would suggest trying exam questions as your first revision method, as then you can identify things you need to relearn or don’t understand. Little and often works best- just 15 minutes a day per subject is pretty effective! Basically, don’t panic! 😁
