The C's are actually merits because he is doing diplomas or btecs, i can never remember which but they are equivalent to 1 a level each. The U is his a level. He really wants to go to university and do music production but the course he wants to do requires CCC. I went to university with CCU grades and ended up with a 2:1 but that was a long time ago and i think they expect much higher grades now. Also worried that if he gets in to university he won't be able to keep up as he is struggling with his a level now.
