Gcse help!!

I’m in year 11 just started and my science grades are bad in my year 10 mocks I got a 43 how do I revise for science and what should I do for each science topic plss help I really want to increase my grades!!

I'm in year 11 and havn't taken exams yet, but my friend got all 9s and she said making flashcards is really good because writing the info down helps you memorise it and then doing active recall with them once you've finished. She also said recording yourself reading the flash cards, leaving a space between the title and the info to guess, is great for when you're on the go and on the way to exams and etc. Also mocks are good because she says they basically repeat the same type of questions so then you know what the exam boards are looking for. Hope this helps

do you have any tips for physics? like esp the equations should i memorize the whole of it or like how would one study for physics 😭I’m really struggling
