I got 3 C's at AS last year (not brilliant I know, but I was happy with that and achieved way higher than my teachers predicted) so I am wondering roughly what grade i need at A2 to maintain a C? Would i need to achieve two C's at both AS and A2 for my overall grade to be a C, or would i be able to get, say, a D at A2 and still get a low C overall? Thanks
