Usually didnt study. gettin a uai of 90 odd, i suppose.
But I think doing 2 or 3 hours a night is all you need, depending on you subjects.

Maths you can just understand something and you dont need to do any work on it.
Other subjects, write your own syllabus summaries as you go, maybe 20 minutes a night.

Assessments, work really hard on.
Exams, do mad cram sessions.
Final exams, start study as soon as you finish school for the last term. (minus a weekend to have fun)

I think important in a study regime are consistency and balance. Dont let stuff you need to do build up. Do go out on weekends!
