I hope this helps!
I tried learning from the textbook (I do OCR) but I feel like they give way too much info and don't highlight the important points that you need to know. Physics and maths tutor is really useful for notes, I recreated their notes in a way into the cornel method as I find that the easiest to learn from and I added my own extra notes to make sure I covered each topic.
I used the website uplearn to help me get to grips with the exam questions as it's one thing understanding the content and a whole new thing knowing how to do questions. Uplearn helped me through the steps to exam questions as well as make sure I covered everything in the topic. However, you can always use some past paper questions and mark schemes to do this lol
Also, make sure you make all your flashcards or whatever revision materials you like to use before your assessments so you're not just spending your time making your resources when you should actually be learning it.
also always make sure to then correct these questions and figure out why you got them wrong.
