You think its hard and you're struggling for 90% of the time but then at the final 10% when you actually put in the effort, everything isn't actually that bad.
When it first starts out, teachers begin with the easy stuff and you think to yourself "why were the year above complaining," as you get 100% in your first mock assessment for the unit.
Then up until December things gradually get harder but you remember that 100% that you achieved at the beginning of the term and think there is no point revising.
January time comes and you have pre-public exams (mocks idk what you wanna call em) and then everything crashes and burns from there after but your habits from Sept-Dec are still there so it isn't till study leave that you ACTUALLY start revising by then it's too late but things are so much clearer.
Just keep revising from the outset and I don't mean read over your notes every night, make all your revision notes ASAP
As soon as the unit is learnt, make the revision notes - my mistake was making the revision notes day before exams and not having enough time to go through them thoroughly
