<p>In high school, I was very good at physics.</p>
<p>However, when I started university, I decided to be a biology major because I planned to go to medical school. I am in my third year now, working in a molecular biology lab.</p>
<p>I now believe I made a mistake and should have stayed with physics. I am always wondering about whether I would be happier with physics. What should I do to gain more experience in physics? My semesters for the next year are jam-packed with molecular biology courses.</p>
<p>Hmm. If you don’t have room to take physics electives, you have limited options. Here are my ideas:</p>
<ul>
<li><p>Do research in a biophysics lab (or some other kind of physics lab, but with a bio background, biophys would be more likely to take you).</p></li>
<li><p>Take physics classes during the summer, at your own university or somewhere else.</p></li>
<li><p>Punt med school for a year or two to work, and take physics classes as a special student while you’re working. If you get a job in a university lab, many schools will let full-time employees take a limited number of classes for free or very cheaply.</p></li>
