Wesleyan is characterized by the simultaneous freedom and seriousness associated with its academics. While students certainly like to have a good time, they put academics first—not because they are obsessed with grades, but rather because they are truly interested in what they are studying. The lax gen-ed requirements allow students to take classes they want to take, and apart from the occasional easy math/science class students take to fulfill a requirement, most classes are challenging and engaging. Professors are very present and available to students, and most are super friendly—it would not be unusual for a professor to invite his or her students to have lunch with him/her to continue a discussion from class.
Course selection, however, can be an arduous and frustrating process, as there are often so many courses that sound interesting, but are hard to get into. The registration process includes a confusing chart that you make for yourself with first and second choices, and then everyone's preferences are plugged into an algorithm. After you get into your initial classes, you participate in a "drop/add" period, where you basically beg professors to let you into their classes and they either say "yes" or "no." The whole process is rather stressful, but the quality of the classes you do get into makes up for it.
