In orientation week there are service activities, you could probably skip them if you hate meeting people but t's more social than anything. Neither research nor service is required, but both are available. Lots of free clinics/outreach is available.
Not an M1 anymore but usually class 9A-12P? Can watch recorded lectures online if you want. Anatomy is different as it will have dissection every other day for about 3-4 hours. Classes often have (mandatory) labs 1-2 times a week in the afternoon where you are taught in a small group setting. Overall M1-2 is pretty chill, lets you direct your learning however works for you. Wellness here is actually giving you time off to do other stuff and have a life rather than obsessive mandatory lectures.
