M-F you'll be in the hospital from 4:30 am - 7:00 pm. You'll have overnight calls about once a week depending on how many 3rd year students there are. You can stay for an elective if you get an attending to sponsor you, which isn't hard if you have a good personality and "the look". I'm currently here for a non-surgical elective and it's great. The attendings, especially the preceptor, as well as hospital staff are generally very nice and helpful.

The BU residents are pretty cool and will take the group out to eat/drink if they like you. They will sign for your meals if they like you and they will take you out to eat during your call if they like you. If they don't like you, they'll tell you to read in the library or to go do something else.

All you really have to do is work hard, prepare for your cases, and not be crazy, but unfortunately that is very difficult for many Ross students.
