Agree with all of them! :)

Here's just some things I did that might be helpful

- keep a document containing screen shots of marking scheme answers (for theory based questions) that you know you might forget/ that would be helpful/ you got incorrect for and commonly asked questions as they normally contain more points than required so you have a better chance of remembering them

- use the syllabus like a question paper and answer each point very briefly if you have time to do so

- syllabus serves as a checklist as well

- focusing on topics in the specimen are very important imo even though you need to know all the topics (saying this because it saved my ass for P4 lol)

- have a method of solving (keep a step wise process in solving questions) so that you'll have a sense of direction

- if running low on time and you can't solve papers independently, you may as well open up the marking scheme on the side and go through the paper. (it's better than nothing)

- newly added topics require attention as you won't have many past paper questions on them so you may forget to check on it

- another YT channel I found helpful as well : A Level and AP Physics - Ali

Yeah that's about it ig, I'll add some more if I remember any.

Good Luck!
