SJC is a unique school for a particular student. If you're that student, it's amazing. If you're not that student, it's hell. The classes are tiny so absolutely no hiding (seminar has less than 10 students with two tutors). Students are really smart. Obviously, lots of reading very difficult books. You need to be able argue your points in class.
You say it's your safety school, likely because of its admission rate. However, they rely on students to self-select so the amiss ions rate is misleading. Instead of getting a report card, you will sit in a room with all of your tutors (called don rags) and have them give you an oral assessment of your performance. It's not for the faint of heart.
The great books curriculum is tough. Check this out:

Definitely worth a visit. Campus is small but lovely. Lots of history and cool traditions.
