Okay so i also do geography aqa and edexcel english. I do aqa science but triple instead of combined but the tips i give should still hopefully be similar.
For geography as someone thats been able to get 8-9s throughout mocks and end of unit tests the best tip i can give you is learn the case studies. Make sure that you know the specific case studies that your school does then memorise as many key facts for them. make sure that you know all the physical geography formations because you will likely get lots of 4 markers in these. practice reading os maps- this is what caught me out in the year ten mock and made me lose a few marks. theyre only 1 markers but 5 1 markers lost could be the difference between a grade. be realistic with your revision. for example, if you study malaysia for the living world you dont need to know every single advantage of deforestation. instead 2-3 key facts for each topic that you have learnt well will help you get a good grade while spending your time well. and also make sure to do past papers. you can find these on the aqa website or can get exam style questions for about a five pounds from cgp.
for english lit i would say its all about practice. at the start of year 10 i got a 5+ in my mock and i got an 8 in my most recent one. pmt has super useful theme and character key facts which i love to use. you also need to know quotes. quizlet and physical flashcards is how i learned these. i would recommend around 20-30 quotes per book but i know people who only did 10 and managed to pass so dont stress yourelf out too much. make sure to do lots of essay plans and then write essays practicing them. you can then give your teachers these for feedback. i would also recommend learning specific context which can make you stand out to the examiner. for example for aic instead of saying preistly was a socalist you can say that he was part of the labour party and advocated for a welfare state.
for english language the main thing i would say is practice. its for sure hard to revise so this is the best i think you can do. i would also say if you struggle with creative writing you can practice writing a high mark one (keep getting your teacher to tell you how to improve) and then try learning that for the exam. im doing this for english language paper 1 tmrw.
for science cognito, learning your required practicals and summary notes are the most useful. then consolidating your knowledge with past papers. especially in bio markschemes are so strict so i think its impossible to achieve an 8/9 if you dont practice past papers and know what your examiner wants from you.
i dont take photography but i have a lot of friends that do and i think their bigggest regret would be not staying on top of their coureswork so make sure to do that
i take spanish not french but practicing key words and phrases for my speaking exam was super useful. i also found it useful to practice lots of photocards and roleplays for your speaking.
maths just practice loads. corbett maths and maths genie are great. tbh i wish i had started doing this earlier because there is so much content along with other exams so starting early can get you a head start
revising for mocks and end of terms as if they are the real thing makes gcses so much easier
