Hiii, I also do OCR A Level Law and do crime, tort snd contract. (I despiseeeee contract so much 😭)
For revision tips:
Make mind maps for section B (problem qs) and and learn the evaluation essays reslly well too.
put them as your main priority as they are 60/80 marks and you can still so amazingly well with just that.
Section A for P1&2 is just wayyy too much info and is less important as its only 20/80 marks so should be bottom of priority. I personally just use flashcards for section A topics and try to just learn the main points for the 12 markers and then hopefully you can waffle your way through them to get at least 10-14/20 in section A which will aid your grade massively.
If you want just a B, stick w just focusing on section B and eval and leave section A tbh, but if your aiming for A/A*, learn it all super well.
What i do for section B is to make a mind map of a topic w all the cases and points of law, make it colourful/memorable for me, memorise it by blurting the mind map until i genuinely know it all off by heart, and then if i have time and willpower, do a past paper q on that topic and get a teacher to look over your A02, as your A01 should be perfect if youve memorised it well.
Hope that helps
