Please Help Gcse Revision!!! Thanks

Do we start revising for our GCSEs at year 10

You'll forget it all so quickly since most of GCSE stuff is about remembering loads of facts rather than understanding concepts, wait until around March of Y11, that gives you PLENTY of time. Trust me in Y10 you need to be focussing on doing amazingly on your controlled assessments but the exams are just a memory game, it's all about short term revision
(I'm currently doing my GCSEs and I've revised for each one the night before and they've gone great so far- I did the same for my mocks and got all A*s and As)
