Normal classes are M, T, Th, F 1:30-5:30. Right now they are recorded and posted the next day so attendance isn't mandatory. However some blocks have small group conferences for 2 hours during that block of time 1-4 days a week that aren't required, but are extremely helpful and I highly recommend attending as many as you are able. You also have hospital mornings every other week on T, W, or Th am, 8-12. Those weeks you also have FCM 1:30-5:30 on Wednesday, attendance required (yes, they take attendance). On the in between weeks starting in January you have your primary care practicum. Most people do this Wednesday AM 8-12, but it is up to you to make a schedule with your preceptor.
Exams are Monday or Friday morning at 8:30, and they will be in person for your class, at the health science library. Most blocks tend to have Monday exams.
There are also always lots of seminars and panel discussions in the evenings that are super helpful. Most of these will be on zoom, unless it's a hands on workshop.
You should also plan for spending at least a couple of mornings or evenings outside class hours shadowing every month, but that's totally up to you.
Hope this helps!
