Studying methods???

A Level student here. Personally, I found reading notes quite passive and time consuming, so you're right to look for other ways. Since you can't take notes home, don't stress about making them. I would just use pre-made online flashcards (like Quizlet or PMT) to test your recall, or try 'blurting' where you scribble everything you remember on a blank page.
Even if you don't have tests right now, i would try to revise consistently for 1-2 hours everyday just to build the habit. During those 1-2 hours, review your topics and use the weekends to go over the hardest questions so you become proficient in them. You will thank yourself on results day by building this routine.
For breaks, 50/10 is totally fine if you can focus that long, but during that 10 mins make sure there are no screens just do some random exercises lol, or get a snack or some water. I would not worry about the library; us older students are way too stressed about our own exams to care if you're taking up space. Hope this helps!

Thanks so much, its nice of you to reply. How much do you study? Im trying to get a coupld hours a week but becuase of after school activites i usually fit them in days like tdy where im not doing anything. Also do you have any recommendations for where i can get past papers, I really cant find any online. Thanks

I study about 1.5 hours a day outside of school on a weekday. Weekends, I try to get 3 hours each day. I would say PMT is a really good website for past papers in Maths, English and the Sciences. You could also try revisionworld, which has past papers in many more subjects than PMT.
