Medical school applications are based on soo many different factors, and quite abit of luck. Just because an applicant was a wee bit worse at one of these factors than the other applicants, doesn’t mean that they’ll be a worse doctor. There are simply too many people applying that would probably make excellent doctors, the medical schools have got to pick people somehow. Yes you can increase your chances. But even so... The fact that they bothered reapplying shows that they probably have enough motivation for the course, and possibly more work experience.
Personally I would be abit irrate if I was in a reapplicants position to be told that I am a worse doctor, just because my hobbies weren't up to scratch 7 years ago.. :P
The medical school application has nothing to do with how good a doctor you’ll be. Its the next 5/7 years of training, and how you adapt to it that decides that.
On a side note.. Its kinda hilarious seeing Gizmo somewhere thats not the new media medicine forum.. =D
