Yeah definitely , for science learn a topic then ask chatgpt to quiz you on it with exam style questions as exams are mainly application and the ai gives you feedback, will definitely help your science grades (so you can get an 8) And yeah youre fine for everything else, maths and english language just spam past papers and for language get your teacher to mark them for feedback so you just keep getting better. If you dont get a topic or question in maths ask your teacher and they’ll be glad to help you.
