Hi! I've been getting 8s and 9s only for RE on every single test and mock and I'm going to take A level RS next year. Here is some advice I can give:
Make sure you know enough quotes to cover each topic and I would advise you to pick them yourself as the quote banks on the internet are not the best. Have a look at this YouTube channel, it's amazing for revision
https://youtu.be/3Lm-Qz2NQQo?si=HoWThOA-47Wq26Ij Obviously know the content well, make flashcards or mindmaps, whatever works best for you.
Also, here is the way you need to answer each question which is very important:
2 marker - give few words for each point, DO NOT explain anything
4 marker - point, explain, point, explain. You can fit it into 2 sentence but I prefer writing in 4.
5 marker - point, explain, point, explain, quote(it can be anywhere in the answer). It would be good if you were to state 1 quote and 2 different interpretations, than explain them. But it can be simply point+explanation and point+explanation+quote, it's also totally fine.
12 marker Paper 1 - Short introduction explaining what the statement is asking(never write anything like "In this essay I'm going to write about...", it's waffling), 1 Agree PEEL paragraph and 1 Diagree PEEL paragraph, another Agree or Diagree PEEL Paragraph if you have time, conclusion where you state which point you find the most convincing and why.
12 marker Paper 2 - all the same except you write 1 paragraph about religious view that agrees with the statement, 1 that disagrees and 1 non-religious perspective.
Evidence doesn't have to be a quote and a quote doesn't have to be from a religious text, you can use a reference to an event, case study or what Pope said, for example.
I hope you found it helpful and if you have any more questions feel free to ask!
