year 10 / year 11 experiences with gcses

As someone in Year 10, I have been wondering if I should start revising for my Gcses next holiday or even now? I just want to find out everyone's experiences with gcses as I want to attempt to get 9's in majority of my subjects. It would be nice if some people share their grades/exam boards and etc. so I know what to prepare for

It depends what you mean really.
When i was at this point in year 10 i did work outside of lessons however it wasn’t that i was specifically revising for my GCSEs as such. I mostly made revision resources for subjects like history and English and for sciences and further maths i made sure i understood all the content we had done.
If you want to spend some time outside of school at this stage then i would strongly recommend making yourself some resources as you go on the content you’ve covered to refer back to in the future. I was so thankful for the resources id made earlier in the year when it came to my end of year 10 mocks and then into year 11 the resources i had were invaluable. Here’s some ideas (based on what i did) for the subjects i did:
English lit (OCR, 9)- learn fully analysed quotations for the texts/poems you’ve done, make mindmaps on context, characters, poems, themes etc
English lang (AQA, 9)- do practice questions regularly to get used to question structures
Maths (Edexcel, 9)- do practice questions regularly (Corbett Maths 5-a-day is amazing) and review anything you get wrong
FM (OCR, A)- watch videos on the concepts and then MadasMaths is the best for practice questions in my opinion (I mostly taught this to myself)
Sciences (AQA, 998)- I used Cognito a lot, mostly just make sure you understand everything you’ve done
History (OCR, 8)- Make flashcards on all the content and do practice essay plans because that helps you plan quicker in exams, mindmaps/blurts are super helpful for linking themes and stuff
Spanish (AQA, 8)- learn all the vocab (you can study vocab of later modules even if you haven’t done them yet)
Art (Edexcel, 6)- focus on coursework
Politics (OCR, 9)- made flashcards, learn the 12 mark plan, learn how to write at the speed of sound lol
Btw StudySmarter is the platform i use for flashcards and its amazing- i can send you some sets i made if you need them and do any of the same subjects as i did (Romeo and Juliet, Jekyll and Hyde, ocr conflict poetry, inspector calls, Spanish aqa, ocr history, ocr politics) plus i used sets that other people made for sciences and found them helpful for Biology and Chem especially!
