So most students are spread around Midtown however, I know there are a few buildings where more students live. A few months before classes, our class made an excel sheet for students to find roommates and housing so that was a good way to find other med students to live with if you are interested in that.
Mandatory sessions will differ in number every week and depending on the unit. They are pretty minimal though, I know this week we only have 2 labs and then 2 required histology sessions. I'd say most weeks we don't have to be on campus more than 2 or 3 days. Our class never experienced the old curriculum, however, I love the curriculum we have now! We are systems based which makes the order of the things we learn super logical, and they do a good job of having experts in each field teach the lectures. We also have clinical skills sessions coinciding with the unit we are on which is helpful to tie everything together. I don't know too much about AOA selection beyond what's online, sorry!
