hey there. i'm a third year at stony brook.
here's my two cents...
first two years are tough. especially 1st semester of first year. the adjustment is hard, probably harder than the adjustment to college. 2nd year probably gets a bit tougher, tho you are a bit more used to studying and the material is more interesting, however, you are going thru systems, and one system can be over in a few weeks.
as for research, by all means, do it if you're interesed, but you don't have to. there's plenty of time b/w 1st and 2nd year to go away for a few weeks and do research. at least 30% of my class is doing the MD with recognition thing, but I'm not, and I still did research on my own.
Having come from a private college, I have to say that going to a public school has both its advantages and disadvantages. Of course, I am saving a lot of money, but there is no such thing as a free lunch. Sometimes I wonder what it would be like at a private school. However, ultimately, I know I am getting a decent education at a decent price. I did fine on the boards, as did everyone else that I hang out with. Keep in mind that this is medical school, and you won't be out hanging out at bars all the time like you may be used to. NYC is sorta far away, b/c of the traffic on LI, but first year, I used to go into nyc EVERY weekend and stay there for the entire weekend. It can be done, and people do it.
There are even people who live in queens and even manhattan the first two years. Granted, not many, but people do it. And definitely third year with the option to do clinical rotations in nassau county, people definitely move away from stony brook and into nassua, queens and even manhattan.
People do match well here, and I think most people going thru the school are worried about how they will do and how competitive they are. but as the dean always tells us from day one, people are pleasantly surprised how they do, as Stony Brook does have a great reputation. Last year's match list speaks for itself and was phenomenal. Great medicine placements, great specialty placements, like ortho 5/5 and even a plastics combined 6 yr program, prolly one of the most competitive programs out there. This year, speaking to 4th years, they are all happy with the types of interviews they are getting.
anyway, this is my two cents, if you have questions, reply to this thread. If you really want to have a talk, PM me and we can set something up.
