Hey there,
Well, about half of my class of 89 are applying to postgrad programs. ~20% of my class are going GPR/AEGD, Around 30% of my class are applying to specialty programs. Peds and perio are the most popular. There are about 8 people in my class applying to OMFS, and two or three going Endo. A couple are going Ortho. I don't think any of my classmates are interested in pros though. There is one classmate of mine I know of who is going to go for an MPH (public health).
I'm sure they are all going to match/place into a program somewhere.
How competitive is UB: For out-of-state, About 20% of our class are out-of-staters, which translates to about 15-20 seats a year, so it is very competitive compared to Columbia and NYU for out-of-staters. In-state, it's less competitive than Stony Brook because our class size is larger.
HTH.
