How to do well for OCR biology??

Any revision sources, notes
or tips to pass on for me to get an B/A in biology? Currently working at a C!! For those that got an A in Bio OCR any good tips ??
A-level

I got a 9 at GCSE.
.
I used the CGP revision guide. I made my notes on flashcards along the year, as this ensured that I wouldn't have to rush my revision.
.
then i turned my flashcards into questions, to check that i actually know the content.
.
for example: my flashcard stated that DNA is ....
i would turn that into a question by writing on plain paper what is DNA?
.
^ this is a great way to test if u actually know ur content and even better you would have a bunch of questions at the end which you could test ur self on.
.
also do alot of past papers

this technique is still good for ur revision at A level aswell

I wouldn’t use cgp for a level as they’re quite brief and don’t have enough info for it. I’m getting A’s at as in aqa which is relatively similar I think. So far I have made rough notes in the lesson then used my textbook and teacher ppts to make detailed notes that I type up at weekends and go through on a rolling cycle to ensure I have all the info by writing it out testing and highlighting what I don’t know and each lesson do past paper qs related to the topic
