Then I'd suggest looking at the specification, as this is an overview of everything that you'll need to know. I would also highly suggest purchasing a revision guide if you don't already have one, because this will explain everything you should've learnt already, as well as allowing opportunities for revision techniques such as note taking, mind maps and flashcards. You might also want to find some practice exam questions, so that you can test your knowledge and figure out where you need to improve, these can be found online anywhere.
I'm pretty sure this is the specification, but you can check the OCR website - https://www.ocr.org.uk/Images/309306...ology-j203.pdf
I would recommend this revision guide - https://www.amazon.co.uk/My-Revision...5175539&sr=8-2
This is a link to some practice papers that are free to download - https://www.tes.com/teaching-resourc...apers-12110086
But honestly, my overall tip would be to try and enjoy the subject, it'll always be easier if you do. Hope this helps!
