Some of the science courses can be really tough because some professors want to "weed out the weak" or something, and truthfully, the humanities seem really weak and easy! I guess if you're into the humanities and just want a high GPA this is a good place. But some departments are absolutely FANTASTIC and many of the professors really do care. Overall the classes are pretty hit or miss though.
Some of the best departments in my opinion? Psychology, the languages, chemistry. Linguistics seems popular but that department is shared by Bryn Mawr/Haverford/Swarthmore Colleges.
