I'm wondering if it looks bad if I retake a pre-req in the summer. I took Physics about 7 years ago and got a C+, DO admissions offices told me I should retake it simply because they want prereqs to be more recent than 7 years. I can't take it during the regular terms because a lot of Canadian Med Schools don't count Prereqs and would drop my course load below the requisite (need a full course load)
