predicted grades problem

Usually teachers give predicted grades 1 grade higher than your AS - therefore in your case A*AA - Even if your teachers predict you AAB or ABB there should be know problem getting an offer from an AAB or even AAA uni plenty of my friends did!

Hi guys got my AS results and got ABB and basically i was very disappointed in 1 of the B's and I am 95% sure that I wont get predicted an A in it even though I know I can (at start of the year head of sixform said I would struggle to get CCD) and also I believe it was just a bad paper for me (ie the topics that came up) as I got an A in my mock 2 weeks before the real exam

My question is, will being predicted ABB mean I am at a disadvantage when applying to AAB and above uni's as I will only be applying to AAB or above apart from one (my insurance and would reject it if it was the only offer I received) and be less likely to get offers from these uni's (Sheffield, Southampton, Warwick and Birmingham (applying for A2B here))?

note: I do have relevant work experience in the subject I want to do which is chemistry

thanks for the help
