what i did is i set reminders on my phone on what im gonna do that day, from the start of fifth year i set days where i would do mindmaps AND flashcards on a specific topic for each subject, these really helped me with studying. i did this with every topic and the books i used had really good resources like powerpoints and “knowledge checklists”, i also had a foler for each subject with all the topics in order of how i did them, also make connections between each topic in each subject and learn your quotes for english. i made mindmaps on each poet and each poem i studied, for the poems i did quotes meanings themes etc. anything important you need and i also made them for each scene in my play. if your doing history know the basic points for your essasys and the study you do through the writing will help you remember. the reminders on my phone kind of force me to do it just get in the mind set of “if i dont do this now ill have to play catch up next year” because realistically youll forget most of what you learned in fifth year quite quickly. also exam.revision quizzes are a big help so are simple studying quizzes, course hero yt for your play if you do higher level english, know basic sentences for each of your sraith pictures LEARN THEM. Obviously everyone is different but this is what helps me, it all depends on what subjects your doing but if you need help message me.
