Revision Timetable

Planning Tips

1. Write your timetable in pencil (or make a version on the computer) so you can change things around if necessary.

2. Start by thinking about what activities you can't miss (dinner, clubs or TV programs) and put these into your timetable.

3. Plan in when you need to do your homework to get it in on time 4. On top of your homework time, aim for a minimum of 2 extra hours on a weekday and 4

hours each day over the weekend. 5. Plan to revise for 1 hour per subject each week (this is in addition to homework) fill in

the table below to help you work out how much time you need to spend on revision 6. Fill in the timetable spreading out the subjects (e.g., don't do a whole day of Maths, do a bit

each day) put contrasting subjects next to each other, to give your brain a break (e.g. English and Physics) 7. Stick to the timetable, it will help ensure you cover each subject and spread out your revision.
