Sixth formers, how many hours a day do you study?Watch
Mine is around 2/3 hours, is that suffice?
I thought the general idea out there is 3 to 5 hours or so
That amount is the average of how much time students spend on revision. It would be tedious to consult every student on how much revision they can do, so they usually throw a number that everyone is expected to cope with. For instance, I can't revise for more than an hour daily, because I simply get bored. It may sound stupid, but my total revision before the AS exams was something around 10 hours, and I ended up with an A and 2 Bs.
