In a strange situation. Need to take a couple more courses as pre-reqs for some out-of-province and US med schools. I've satisfied my degree requirements and all signs to me graduating in June. How does it work? Is this even allowed? Also, will this part-time fifth year come under scrutiny of med schools?

Tried looking for some information on this but couldn't find much helpful stuff. Thanks.

The procedure is called "Continuing", and lots of people do it. Any work you do will go on your transcript and would be visible to any place you apply to for further study.
