Mmm, it really depends... I know so many people who got amazing AS grades and got rejected. Others the opposite and ended up with exceptional A2 grades. I know some who also got rejected by Warwick but managed to come out with 3A*'s, called up on results day and literally begged (maybe 4 calls per person), and then got a place. It all depends on the applicant. The grade standards at Warwick are on the AAA-A*A*A* side, with some who get ABB to AAB. Good luck though, no harm in trying. Make sure your references are fantastic as well as your PS. x
