Advice please! Watch
For revision resources, I'd recommend looking at questions by topic on www.physicsandmathstutor.com and maybe have a look at the CGP workbooks too.
My revision advice - practice questions. Note-taking's fine but it should not make up the bulk of your revision. Use your notes as reference for when you're doing questions, don't just read them.
I guess with bio and chem they have to clear out the GCSE misconceptions
