You'd have to resit almost everything, your school would only predict your A2 grades based on your AS, and your unis would find out your AS grades anyway. Unless you can think ofa good excuse to write in your personal statement (and being lazy will not be accepted, you'll be laughed away with no interviews I fear) your'e in a bit of a sticky situation. Best ringing some unis up to see if they'd accept those AS grades if you promised to raise them. OR - I know someone who got a U in an AS, becasue of which almost every uni said they'd need AAA in their 3 A levels, so that might be an option - call your preferred unis and see
