100 hours enough time to learn enough for each subject to get an A?Watch
I can link each one up to my most recent grade at that point in revision in time order. I think 100 hours each is excessive, but if you think it's what you need then sure.
Biology unit 5 - 5 hours - C
Physics unit 5 - 6 hours - E
Physics unit 4 - 14 hours - A
Biology unit 4 - 17 hours - A
Chemistry unit 5 - 17 hours - A
Chemistry unit 4 - 17 hours - A*
Doing 10 hours a day, you're gonna need 40 days. Do you even have 40 days before your exams?
For the easy unit in Physics I'm at an A and haven't started revising at all for the harder one.
For maths I'm at an A in C1 a B in C2 and a B in M1 I'd say but I know much effort won't be needed to pull it up to an A overall.
For biology, well I've done nothing at all so I'm guessing I'm at an E.
