hi, im going into year13 in september, and i recommend using anki for bio. Don't copy notes word for word, and don't be too generic either in ur note-taking. highlight key words and definitions and make sure you have them memorised as soon as you can. I know this is kind of weird to say but try to be creative with it. i mean, personally for me, i enjoy drawing out what i learn in biology because its easier for me to understand what's going on. for example, i make small comic books based off the topic im learning- especially if its a difficult topic. learning a topic visually helps A LOT. try to make it fun- for example, try writing raps and songs, or create a storyline with what you've learnt. As someone who takes Biology, chemistry AND physics alevels, this helps so so much. the more silly it is, the easier it is to remember lol.
also watch youtube videos for topics that you've learnt- I recommend Mr Murray and Miss Estruch. You can also watch freesciencelessons, but personally for me, I don't really freesciencelessons that much bcuz he airbrushes a lot of the content- if you want to understand the topic in depth, mr murray is the best one. after ur done going over a topic, use physicsandmaths to work thru questions on the topic you've just learnt. it doesn't necessarily need to be from ur exam board only- the more exposure you have from different exam boards including ur own, the better it is. (just make sure it's questions from the topic ur learning obvs). and yeah, that's pretty much all i have to say. alevel bio isn't as hard as people make it seem, the only thing that's hard about it is the content. but if ur good at memorisation, n u do a lot of practice questions, you'll be fine
