Is there anything you guys can recommend doing to minimise silly errors? I get 90+ on all the papers and I've only got like 4 more for C4 and have done all of the C3 ones and a few solomons for both. For instance I've interpreted 1/root(1+x) as (1+x) to the power of 1/2 , not -1/2 in a binomial question, or I sometimes don't expand a bracket correctly. It's really infuriating for me sometimes because this can be the difference between getting an A* and an A.
