That is a shame. However, do you qualify as a 'mature student'? Generally grades are waived for mature students and consideration is given for life learning and worldy experience. The mature student needs to demonstrate they are capable of handling the course work. Have you considered this option?

Also, you can still take pre-med courses without being in that study area. There is an option, once all the prerequisites are met to still get into medical school. If you don't then you have the core group of credits for a B.Sc degree.

The real consideration isn't getting into medical school, the consideration is what happens when you graduate it. I think the stats are something in line with 100 applicants for every 1 residency position. Still, if you are determined it is worth a try.
