Blocks were originally MCM (biochem), then MSK, then HDM (immuno), then cardiopulm, then renal in fall semester followed by GI, endo/repro, neuro, and MOD in the spring semester. They're combining MCM and HDM for you guys, then there's MSK, and then you have neuroendocrine for like 8 weeks after that (don't even understand how neuro and endocrine go together...). Then in the spring you have cardipulm combined with renal, GI/GU, and then MOD-- I'm not looking at the schedule in front of me, but I'm pretty sure this is the order.
They have also added a fall break, given us a 4 day weekend for Labor Day, added more independent study days to make breaks longer (so Thanksgiving break will start on Tuesday this year).
They are combining some things in second year for us as well, but it seems more weird in first year to me for some reason.
Positive changes are less frequent exams, more free weekends, consistent scheduling (so OS lab will be on the same day every week, rather than randomly scheduled like it is for us now..makes it really hard to plan any outside activities or hobbies). Unfortunately, only time will tell how this turns out. I am personally pleased with how this looks for us, as I like the predictability it will provide in my day-to-day schedule.
