I'd just say if you really don't like it and feel in your gut that you do not want to do it, switch courses. I started AS last week and am doing English Lit, Biology, Art and English Language. I have already swapped graphics for art and tomorrow I am changing to english language (from history). This is down to me having a few lessons in graphics and history and thinking oh my god, I cant do this, I don't want to do this... My college lets you switch courses in the first few weeks, and that's great! I don't know what I want to do at uni so for me, I've tried to keep my options open a bit; an art, a science and english lit and lang.
