GCSE revision timeWatch
What subjects are you revising?
I feel like 6-7 hours is a bit excessive and if you aren't feeling satisfied it's most likely that your revision isn't effective. Although, it depends on where this feeling is coming from, are you doing well in your mocks and revision papers?
It’s also be much easier to increase your study time in year 11 as you’re already building up your stamina and work ethic.
Personally I’d advise creating and following a study timetable. This will help to keep you accountable and also increase your satisfaction with your revision as you can see what you’re achieving.
