GEM course accepting biomedical sciences specialising in biochemistry over a level?

Hi

I was just wondering if anyone knows of any med school which will accept a specialism in biochemistry over a level chemistry requirements. My a level grade was a C (one mark off a B), but my biochemistry modules are all firsts. Obviously, I'll email them all with the module details etc. but I just want an idea of if any allow it. Having the C in chemistry is very restrictive as to where I can apply.

The module titles I've done are: Introduction to biological molecules, Clinical biochem and analytical biochem (and next year research topics in biochem if I get the biochem specialism- we don't find out until september). These modules have covered pretty much all of the a level syllabus.
