You definitely would be better off going to UCSF vs tufts. I have friends in tufts, and who have graduated from there. The cost is exponential. Think about it from a point of view as if you've just graduated. Think about the debt. Every dollar more you spend is less in you and your families pocket. And, if trying to buy in to a practice, or start your own, being over $300grand in debt can make that quite difficult.
Not to mention if your dorming there, its communal bathrooms and cramped locations. (As I said I have friends there)
I interviewed at UCSF, it was beautiful, spacious and overall a great experience, compared to the congestion of boston and cramped school. Which not to mention is currently undertaking 2 years of contruction on there dental school, breaking up your lab/clinics.
And the kicker- The elevators are being shut down so all will be required to use the stairs to travel up to the clinics and classrooms.
Definitely look UCSF instead of tufts.
Good luck!
