Is it very likely that I could go to Cambridge or Oxford if I did do badly at GCSEs? Would I really need 9s and 8s in all subjects? What happens if I perform amazingly at sixth form but got 7s and 6s and 8s for GCSEs? Do I have no chance? I would really like to study engineering at Cambridge or Oxford in the future but I am not sure I can get amazing GCSEs. Would I have a sliver of a chance? What could I do to increase my chances?
Do they actually matter?
