Hi, I'm a third year maths student at Lancaster University and thought I could suggest some revision techniques that I use that might help you, especially with maths.
First of all it's a good idea to create a revision schedule, this will help you stay on track and cover all you want to. Make sure it's a realistic schedule though, you don't want to be doing too much revision at once because it can be hard to remember the stuff you've revised after revising for a long time. Also if you miss a bit of revision you were intending to do, don't worry about it, everyone needs a break sometimes and you can start revising the next day with a fresh mind. Here are some methods of revision I have used for Maths:
1) Doing past papers is one of the best methods of revision, it helps a lot with exam technique and also shows you the kind of questions you may be asked. Just skip over questions that you haven't learned the material for yet. To make this technique even better, it's worth doing these papers at the same time as your friends and then marking each others work. It can be very helpful to see other peoples methods of attempting questions.
2) If you are struggling with a particular topic, it's worth doing all the practice questions you can find. There's lots online if you run out.
3) In addition if you don't understand a topic, it's very worth going on youtube and searching it up. There are lots of brilliant videos explaining topics and maybe they'll describe it in a way you understand.
4) When I was doing GCSE Maths I really found the Corbett Maths flashcards helpful. It helped me sort topics into ones I knew and ones I needed to do a bit more work on.
5) Sometimes your teacher will run revision sessions, theses are really worth going to. If they don't run them, it could be worth creating your own study group.
Here's some advice for the other subjects that I did at GCSE:
French: Making flashcards of key words you need to remember is so helpful. I used to use quizlet but it was free then and now you have to pay for most of the features. I think there's a good alternative that's called Anki. It's also worth going over all your tenses and conjugations and making sure you know any irregular verbs. I also found using Duolingo helpful.
Science: Lots of the techniques mentioned for Maths above are really useful to revise for science. Definitely go over some past papers. The CGP revision guides are great help, if you have access to them it's worth using them with your friends to test each other. Also it's worth practicing some of the longer mark questions just so you get a feel for what they are like.
I hope that helps you, sorry I can't help with revision techniques for Media Studies and RE. Good luck with your mocks and let me know if you have any questions
