Wilt - I think you need to review your method of revising. When I say "I revise", it doesn't mean I endlessly read revision books. No. I vary my technique. Sometimes I read it aloud, record it on to my mp3 player and then play it back. Sometimes I draw little funny cartoons to help me remember things. Sometimes I just condense the information into a few keywords.
The thing is, apparently you only remember 20% of what you read, 30% of what you hear, 40% of what you write , 50% of what you see and 60% of what you do. Now considering these statistics, the least memorable way to revise is raw reading.
I agree, alot of it is memory based but I think you do have to be intelligent to get a higher grade. Take the double science AQA paper on wednesday for example. There was question about Bromine and Propene I think. Yes, you can remember the structure of Propene, and you can remember what group Bromine comes under and its associated chemical properties - but no book is going to tell you how to do ALL the possible chemical equations. Like a maths revision book: it can tell you what tools there are and how to use them, but the exam in practise is testing how WELL you can use them.
People still make mistakes using the quadratic formula - even though its usually printed on the front of your exam paper.
So in conclusion, its NOT all about memory.
Piglette - I also take GCSE Art and I can empathise with you, but I think you got yourself into that situation because you didn't plan how much time you'd spend on each subject. In my opinion, Art is the LEAST important subject; how many jobs will ask you "What did you get for GCSE Art?" Of course, I love musical art because I play guitar. But that's not important. It won't make me become a physician, psychologist or ICT consultant.
