Including A-level results on CV for sw applications

Hi all,

I got into a strong semi-target university with much lower grades than I was expected (got BBC, expected A*AB). My dilemma now is do I include my A level results on my CV when applying for spring weeks, or should I just include those grades when specifically asked for when filling out forms? I have a pretty solid reason for the C, same with one of the B's, I just don't want my past grades to close all my doors. I was thinking I could instead mention some of the projects I've been working on this summer (quant analysis stuff I made in Python, studied core of MPT) to buff my CV up. Thanks for reading
