Thank you everyone for your reply. I probs should have made it more clear I'm studying in England and last year I was taking biology, photography A2 and business BTEC as my a levels.
As this September comes around I have finished photo, I didn't like business and therefore I also need courses to do at my sixth form as the requirement to stay is 3 courses. I got back to school on 31st so I'll probably have to have a long sit down with the sixth form team as to what I do, I wish I had just taken chem for year 12, but hey ho, I've just got to go on now.
