First of all, as an M1 I should put the caveat out there that we have been in pandemic mode since day 1, so our year has looked different from previous years and I have nothing to compare it to.
We all take a different approach to our learning. I like to go to lecture (and by "go" I mean stay in bed and watch pre-recorded lectures on 2x speed) but I have classmates who never listen to lecture and use Boards and Beyond, Pathoma, Sketchy, and Anki instead and seem to do just fine. We have a couple of mandatory activities every week, plus mandatory anatomy on some weeks, but mandatory activities take up perhaps one or two mornings or afternoons per week. The rest of the week is pretty flexible.
I do think that one could, especially as the year goes on and they get the feel of medical school, study more or less on a 9-5 schedule assuming that they didn't go to live lectures (in other words, waited for the recording to be posted and listen to it later). The exception to this is that anatomy tends to start at 8 am when we have it and that sometimes the weekly exam(s) on Friday morning start at 8 (but sometimes they don't - it varies week on week). At the beginning of the year I basically studied from 8 am until late at night, but eight months in, I now work from about 9 am until 8 pm, taking breaks for lunch, a walk with my dog, and usually a workout at some point in the day.
I don't find that I have a ton of free time during the week, but I always am able to have dinner with my spouse and am almost always able to take weekends off.
Regarding faculty...it depends. First of all, since we have been doing remote lectures due to the pandemic, we have not met most of our faculty. Also, OHSU brings in different professors for each lecture, so in a week we may be taught by 15 different people, some of whom we may see for one lecture and then never again. Our block directors - the faculty who run each independent curriculum block - are variable. Some of them are super interested in the students and some are less so. The block directors are constantly asking for feedback, but whether they act on it or not depends. Some are better than others, in other words. We have a handful of faculty who are superstars and bend over backwards for their students - these tend to be the faculty members we see the most of, so that makes sense. I also get the impression that a lot of our professors would be excited to become mentors if students reached out, but given the fleeting nature of their relationship with us, in all likelihood, they don't hear from many students. We also have great deans who are very receptive and interested.
On the whole, I have found OHSU to be a great place to learn. Like any university, it has its challenges and its failings, but I think OHSU does a good job and feels like a supportive and flexible place to learn. BY FAR the best part about OHSU is that it deliberately fosters a culture of cooperation and support among the cohorts. The Med24s are collaborative to the degree that we freely share resources, tutor each other, remind each other of upcoming deadlines, and generally bolster each other through the storm that is medical school. I think the university does a pretty good job of teaching us, but what makes OHSU stand out for me is the camaraderie of the students.
