Before normal exams i felt it was best to study till about 11.30-12 then sleep.
For HSC and trials i stayed up past 12 and sometimes finished at 1.30 am.
But it depends what time you need to wake up.
English: Perfect your essay notes for each part. Create a 15/15 story early in the year
Math: Like everyone says, practice makes perfect
Chem: Try to understand everything fully then cover your dot points. (Do a lot of trial Q's as well as Past HSC)
Legal: Not hard, just have notes on syllabus and....yeh you are set
