I have been rejected by Warwick which is the one I really want to go, for the BSc Economics and Industrial Organisation. I was very surprised and disappointed. My predicted grades are A*AA and 6A* ,4A and 2B from my GCSE , I believed that is good enough to get an offer but they don't think so. It may be my As result ( high A in Economics, high B in Maths. and Biology ) or my personal statement and this is only one course different from others ( other 4 universities were applied for BSc Economics and Management ). So should I contact them to get the feedback ? And will ( can ) the university change their decision ?
