I think you should probably try talking to your teachers whether you can get a better predicted grade, because that seems a little bit borderline. Some universities do give offers if you are a bit under, but are probably less likely to. What were your grades at AS level?
If my predicted A-Level grades are A*BC, what is the likelihood of me getting into a biomedicine course at uni which requires ABB?
As I understand it medical courses are quite competitive, so you might find it difficult, but you should still try. I also heard that if they ask for ABB, they won't accept a grade that's below a B.
