<p>Sorry for the late entry, but I would echo what Hanna said for sure. I'm a premed, but I also sing in an a cappella group and am involved in the Crimson, a service group, and a social club on campus. Balancing extracurriculars and classes can be tricky at times (mostly b/c everything here is so cool you want to do it all) but it's very manageable and you definitely still have time to go out on the weekends and have fun with friends and whatnot. </p>
<p>I would say another thing to really emphasize is that the courses are all curved to a B+ or a B (freshman courses like intro bio and gen-chem are B+, orgo and higher level Bio are B). Now I know that after a high school career of mostly A's or A-'s (especially in sciences) B's sound repulsive. But consider this: of the students at Harvard who applied to medical school last year with a 3.49 or above, 100% were accepted, and of those with a 3.19-3.49, 97% were accepted. That literally means that even the kids with B/B+ averages all got into medical schools.</p>
