<p>I don’t think anything you do during the college application process other than pick a school that you will do well in and that has a good medical careers committee will affect your chances at med school. It is what you do in college that Med Schools look at (GPA, Volunteering, Research, MCATs). </p>
<p>However, you may want to explore if a medical career is for you now somewhat by volunteering at your local hospital/nursing home, etc. You would want to take challenging science classes to ensure that you like them and are good at them.</p>
