Dear OP and anyone else in the same situation. Don't let your subjects at A-Level define what you have to do for the rest of you're life! I did business at A-Level and have since applied to do archaeology after taking a few years out to get my head sorted and find out what I wanted to do in life. Suffice to say because I demonstrated strong enthusiasim and motivation in my personal statement about my love for history, I have been given unconditional offers for archaeology at York, Manchester, Newcastle and Sheffield! Honestly as long as you present yourself in he right manner and come across as a high achiever for anything you set you're mind to, then there really aren't any limits! I wish you all the best!
