I got all 9s in triple sciences and here are my top tips:
Notes are okay, they can help consolidate knowledge but the thing about sciences is that (for AQA at least) the mark scheme is very specific. If you're writing notes, take them straight out of the CGP guide so you're using the right wording. Your teacher probably tells you to write notes to help you in yr 11, but tbh this wasn't really helpful for me.
Definitely do as many practice questions as possible!! Instead of writing notes, I wrote out any questions I got wrong or ones that were common in past papers and also wrote down the answer on the markscheme. This helped me 'make notes' and practice at the same time, and I only noted what I genuinely didn't understand.
I use physics and Maths tutor and Study mind as they split them up into topics. If you find making notes time consuming, the mind maps and summaries on PMT are great to use.
Another amazing resource is the CGP revision cards. I only got them close to exams but they were a lifesaver. Everyone sells them on eBay so you should be able to get them at a good price.
Obviously whether this helps you depends on the sort of learner you are so do think about what suits you, your strengths, and weaknesses. Also, yr 10 is a good year to experiment. The best revision techniques are a mix of lots of different things.
Hope this was helpful!
