Woah.. that's pretty intensive. I tried doing that kind of thing last year, and the plan failed. Dismally.
So what I'll be doing this year are just daily plans/timetables. I made myself a set of timetables on Word that I printed out so I can fill in one a day. Some timetables are set in increments of 30 minutes, some in 1 hour. Basically what I'll do when I get home from school is jot down everything I need to do for that day, and allocate time accordingly. This makes your study/homework more specific to your needs and tasks. Having a clearly defined timetable lets you know how effectively you've spent your time too - for example, at the end of the week, you can scan through all your daily plans of the week and see how well you managed time. So I guess the main thing is to be specific with your study.. don't allocate 8 hours of study for every Saturday or whatever when that's not going to be the case for EVERY Saturday of the year.. I know it's important to have a fixated routine in VCE, but it's important to have flexibility too; and that means tailoring each day's work to what you really need to focus on.
In year 10, our history teacher used to give us surprise, random tests. She would never tell us when we were going to have a test, or what would be on the test, because she believed that you should be revising as much as you can on your own, and you should be able to work out what you need to work on and how regularly you need to work on it. I think this is important - you need to be able to have that feeling that if a SAC were to be thrown right at you, you'd be able to do it well.
(By the way, if you want some of these timetables I made up, I can email them to you.)
