Hiya, I think it depends how you study best and also what subject you’re doing. At this moment in time, I think it would be good to do lots of practice papers and go over topics that you aren’t as confident in to help you pick up the extra Marks
As for revision timetables, be careful about these, just make sure that you’ve split each subject up into sections and have a healthy balance between working and resting as you don’t wanna burn out
For subjects, like English, history and geography, I’d recommend using flashcards and having a look on YouTube for videos to further aid understanding . Quizlet is really good, and it already has premade flashcards, and could be helpful to make different topic revision summarise.
Good luck with your exams and let me know if you have any more questions !
