First of all, calm down, and give yourself a pat on the back. 3.5 is a fine start. Next, start thinking about the pursuit of medicine as a journey, not one to be achieved or denied by one victory, nor by one defeat. So many things play into getting into medical school and becoming a good doctor. I know, tough to do when you are a Freshman, and everyone tells you that you need to be Albert Einstein to be a doctor. Not so, work hard, have fun, live life, and be diverse. The last thing a med school adcom will want to see is someone who worried about a 0.1 GPA boost, but spent all their time tucked away in the corner of the library, leave that for your M1 year. Keep up the good work, treat yourself to a celebration drink or something.
