How do you revise?

For GCSE, past papers are the way to go! what better way to practice then to attempt previous years' exams. make sure you go over question you get wrong and learn what you could have done to improve. the mark schemes are really useful to go over as well as the examiner notes.
Before you go through the past papers it's important to fully understand the course. I would suggest going over all your class notes to see what you know and dont. Ask teachers to explain things, im sure they will be more than willing to help. Going over the specifications is a good way to see exactly what you need to know for each module of each subject.
Hope this helps!

How are you revising for each of them?

For the sciences and RS I usually just make notes from the textbook and answer the questions from there. I don’t revise English because I have no clue where to even start, I just try to cram a few quotes. For maths I do a few past papers, and revision papers on specific parts that I struggle with. For Spanish, we use a website called Memrise which really helps with learning vocabulary but not really with forming sentences and speaking (even though I probably won’t end up doing a speaking exam anymore). For Computer Science I use flash cards.

Is that useful method in sciences and religious studies or do you forget the content next time and can you answer it without notes? Is this for English Lit? Is the maths method effective or could it be better? So for Spanish, writing and speaking is your worst areas? It's good to revise for speaking since you dont know how they'll do it so it's safe just in case. Idk about computer science so I cant help you with that - hopefully someone can help you with that.

For sciences and RS, it helps me gain the surface level information but not a deeper understanding in order to fully answer contextual questions.
Yes, English Lit, but for both lit and lang I don’t know how to revise at all.
The maths method is okay but it could definitely be better.
With Spanish speaking, we hadn’t started practising it and now it might be removed from the exam so I have no idea of my level of skill in it. With Spanish writing, it’s not completely bad but it’s not quite as good as my reading and listening.

Thank you so much. What do I do when I don’t understand the mark scheme, especially considering the summer holiday is coming up so I can’t contact my teachers?

So when you look at the question, do you know what to write because of the mark scheme but you dont know why and how that answer is that answer? Wdym contextual questions?

How could the maths method be better? It sounds like a good method but if you think it's not helping you, is understanding the questions you want to improve on or do you get questions wrong a lot and you want to reduce it?

Tbh I only revised for speaking when it was closer to my real exam so I wouldn't worry about it when you come back to school and your teacher plans something about it so I would focus on writing as it will help for speaking. Is it the mistakes that is restricting your skill or is it because you dont have the higher level detail in your answer to reach the marks you get for reading and listening?

Btw Im so sorry for answering questions but I like to break it down and make the person think about what specifically they need help with so I can give more specialised advice in context to your problems.
