Not really insightful nor unique it's a lot of things that you already know about, you will find the curriculum in some form or another in every medical school. Time commitment varies, the class runs every other week for 2 hours of large group then 2 hours of small group for phase 1. Then in phase 2 it's reduced to a 2 hour meeting every 6-8 weeks. Outside of that, you have a few things. A community health project which can vary in time commitment depending on what community partner you are assigned to. You and a classmate are also paired with a community member and have to have a call with them every month or so for an hour.
I'm not considering skipping 4th-year atm since I want a surgical subspecialty. Can't comment on that experience at this point since I don't know anyone who has done it.
