<p>Will it kill my chances for admission to med school if i have to re-take the first semester of organic chemistry?</p>
<p>... that depends on why you had to retake it. Did you flunk? (Yes, probably.) Did you withdraw because your mother had cancer and you had to stay home to take care of her (definitely not)? Did you realize you were in over your head, withdrew, and retake the course (a hit but not a fatal one)?</p>
