Can you specify the subject and how your timetable is and whether its on a school day or not.
I'm probably not the best person to ask as I didn't revise much for my A-Levels, they were pretty poor but I got into a foundation year in university, which I would say is the same difficulty as A-Levels just focused on one subject. But for me, the amount of revision I do is based on a.)How much the test/exam is worth and b.) How comfortable I am with it.
I'd personally do around 3/4 hours a day over 2/3 weeks for each test/exam.
Wowee, how do people even revise that much?? I only ever do the homework I get given, so probably around 3/4 hours a week for all three subjects? If there were tests or mocks coming up then I usually do around 2 hours a day everyday the week before.
People on here are stressing me out haha, though I guess it kind of motivates me to start working harder >_>
