<p>Cherrycoke – I don’t think it’d be too late. My academic advisor told me once that he knew a few students who had decided on premed that late and still managed to fulfill all reqs on time. However, I think it’d be smart to take biology before junior year if you think there’s a chance you might go premed. You’ll need to take a science course anyway to fulfill core reqs. And you’d definitely need to work hard to catch up, but it’s doable. Also, if worse comes to worse, you can always take a summer course.</p>
