I'm applying to MD/PhD programs this cycle (for matriculation in 2015). I never got my second semester of physics done while in college, so I'll need to take it sometime before I matriculate. I've had a few gap years but have been busy with a full time research position. Will it look bad on my application if I wait until this winter or next summer to take the class? I.e., should I get started on the course this summer so that I can at least say that the class is in progress? Or does it not really matter? Thanks.
