I had someone come to my school and tell us that 6 hours is about a band 4/5, 6 - 8 hours is a band 5/6, and a Band 6 is around 9-10 hours. Any more than that, she said, with breaks and exercise and eating, is your entire day.
Basically, I wake up at 7 and by 9 have everything done. I've done the whole TV, shower, eating, exercise thing (unless it's training, in which case it's got its own block) and then I study for 3 hours. Then break. TV, lunching &tc. Three more hours. Dinner, whatho. After dinner, I'm usually motivated to do something, usually in preparation for tomorrow. So, I'll organise my folders so when I wake up in the morning, I'm not completely blown away by having to figure out what I have to do.
Past papers make the time fly. I mean, 40 minutes has never seemed so fast other than when you're analysing Clueless/Emma. Two past papers and some organisation, and there's 7-8 hours a day. Sweet.
And now I'm going to stop procrastinating on here, and go and finish those Legal notes. Too right.
