Completely valid concerns. I think one thing that needs to be accepted if you choose to commit to DGSOM is that our curriculum is a work in progress. It's now gone through 3 iterations and is much, much improved from what it originally was. If you're a person that is more comfortable with something that is tried and true, sure maybe DGSOM isn't the best place for you right now. I'll also emphasize that the large majority of the core clinical team are the most passionate and caring educators I have ever met. They also recognize that something is wrong with the curriculum and are actively working to fix it.
Personally, I don't think this should be a major deterrent for students who have other things to gain from being here. I.e. family, location, networking and connections. My only piece of advice is don't drink the Koolaid that you're fine only doing in-house material. Use third party resources. Study for Step 1 all throughout MS1 year and take it before clerkships (even though that's not what the school advertises). Albeit I don't see much of other schools, but the large majority of my classmates are the hardest-working and most competent folks that I know.
