Hey Everyone
I'm new here (yes, a tad late I suppose-- surprisingly even though I'm a senior in college-- I found out about the forums late, so was just a silent observer on the outside).
I'm actually a Stony Brook undergrad and got my acceptance to Stony Brook Med School last month. I already sent in my deposit and the paperwork-- so I will be attending in the Fall.
As WildTumor pointed out-- commuting isn't that bad. I live about 20 minutes away (yes, I fall into that statistic) and I drive in. I've also had friends who have taken the bus or train (the train station is on campus).
Parking near the hospital is about 20-some odd bucks a month, but I take classes at the Health Sciences Center now and park on the undergraduate side of campus for free. The buses though run about every 15 minutes (though they're not on the dot) so that can pose a problem if you're not up for waiting for buses. Otherwise, a walk to the Undergrad side of campus is about 10-15 minutes, so if you want to trek over for food at Jasmine (the Asian food central on campus) or to do anything else on that side, it shouldn't be a huge issue.
It is better to have a car for everyday things though because the grocery stores are at least 10 minutes driving as is the mall (though I will admit-- if you're up for public transport-- there are bus schedules to go to those places on the weekend).
Congrats on getting in!
