If you search up studypetals, or check out pretty much any other studyblr, they have masterposts on tips for studying, cramming, not procrastinating, etc. Additionally, on FB alone I'm in a Class of 2016 group for nearly every subject I do to receive free help with exam questions, or exemplar essays, etc. If you search for the resources, you'll find them.
My own tip is to actively make notes while studying/learning. So active studying rather than passive studying where you kinda just absorb material. Annotate highlighted bits as you're reading your textbook or link it to another part of the syllabus.
Also, I think the most important thing I learnt this year was to know what to learn and what to just let go. Actively pick out the bits of information that you will need the most. That is, anything in the syllabus. If it's not in the syllabus, or it doesn't support your argument, let it go.
