I have been doing loads of past papers, but I ALWAYS get C grades, not because I don't know how to work something out, but because I always make a stupid mistakes, like not reading the question properly or doing the method but forgetting to adapt it for the task (for example, forgetting to times the values by half for working out the volume of a triangular prism).
Any tips? What's the best way to bump up my grade?
Thanks.
