Below is an extract from my senior study guide which may assist you in making a study timetable-the key point to remember is that quality of study is more important than quantity-there is no use claiming you studied for 9 hours if you barely finished any work.

HOW TO ORGANISE YOUR STUDY TIMETABLE:
I think the best way to make a time table is to make it flexible, whether you have a to-do list by day or organise your day into relaxation and 1 hour long study sessions, do what works for you. There are a few things you should make sure to include in your timetable/to do list to make it effective
1)Always be realistic-don't assign excessive amount of work that you cannot achieved in the designated amount of time you have set aside for yourself
2)Make sure you are flexible-so you can make adjustments to your timetable when extra-curricular and any other unforseen circumstances comes up.
3)Make sure you are studying at times optimal to your concentration and alertness level. Don't assign studying at night if you can't concentrate during that time
4)Include social activities, work commitments, relaxation time into your timetable-a balanced lifestyle is essential for long term academic success
5)Make sure you follow your timetable as closely as possible and try not to have too many carry over tasks to add onto tomorrow's workload. With lots of trial and error, you will find a way of organising time that you will feel comfortable with and which works for you
Hope this helps-best wishes with your HSC studies this year
