my #1 tip for school is to keep it simple and sustainable
don't get crazy with your bullet journal with the expectation you'll have that energy every week/month. sometimes its just gonna be a barebones checklist and that's okay! it is first and foremost to keep you organized, dont stress over consistency or aesthetic cohesion. same with your class notes; if you focus too much on the quality of your handwriting you'll forget what you were writing in the first place (ask me how i know)
dont go nuts color coding stuff bc eventually, inevitably, one of your highlighters will die, they wont carry folders in your Designated Color, etc. dont let that collapse your system
dont chunk up your time doing 15 minutes kf math 15 minutes of english 15 minutes of chemistry. you'll go crazy trying to be more efficient (ask me how i know!!! ðŸ˜) and retain less
basically dont spend so much time thinking about how you're gonna study that you don't focus on what you're studying. thats what made me have to drop out of my latin class in college; i was so sure that if i could just devise the perfect system the classwork would just flow and i'd be golden. well i never found the perfect system (bc it doesnt exist) and i went weeks without doing any work bc i was so petrified to start in suboptimal conditions. you know "do it scared"? do it sloppily. do it messily. do it on the back of a napkin. do it with so little fanfare that the anxiety doesn't have time to take hold before you're done.
