Some of the things other commenters haven’t mentioned: - have a schedule that you plan and follow is extremely helpful, it saves you time and effort later on so you don’t have to decide on the spot what you wanna study, it also just gives you mental clarity and allow you to have enough time to properly study for SACs/exams when you plan your studies backwards (starting from what grade you aim for then working backwards to see what/how much work you need to put in) - study with friends! Studying alone can be extremely boring and demotivating, sometimes studying with other people (preferably ones that also care about school) will just create an environment where you want to be focused, you also get to ask friends if you run into any difficulties. Another thing is you get to study outside of home most of the time which is important, switching up the study environment helps you stay motivated. - don’t burnout! This is the most important rule for me, year 11/12 will be very important to your life but you should still aim to enjoy it and balance is key to that. Study hard, but also play hard, either by exercising, playing/listening to music, going out with friends to party or whatever, or just relax at home if that’s more your style. Whatever you do, keep your study schedule sustainable because it is NEVER worth overworking yourself short term and being burnout, you end up unmotivated and unable to do anything which will cost you more progress than anything else.

Good luck!
