Put it this way, I resat my AS year, and i've now finished sixth form with BBC, B in biology and religious and a C in chemistry. my insurance was DMU who wanted ABB but they still gave me an offer. I firmed sunderland who wanted BBB but let me in anyway. Your firm will most likely let you off upto two grades, possibly 3 if you're lucky, seeing as though my close friend got an offer from Huddersfield of ABB and ended up with BBD, D in biology but still got an offer. With predictions of ABB I'd apply to whichever uni you want really. According to the site Unistats the better unis are Nottingham, Huddersfield, DMU etc
