Transferring to SUNY Stony Brook from CUNY Hunter

<p>Hello,
I am a first year student at CUNY Hunter and I would like to know my chances of transferring into Stony. I was accepted when I applied in senior year in hs (i had a 3.4 avg and a 1190 math&reading SAT score), but i chose Hunter because I had to stay home for a while. Now, I'm looking to transferring for my sophomore year, Fall 2015. By the March 1st deadline I would have 20 credits earned. My intended major is Chemistry, but at the same time I am looking into the Information Systems major. I want to pursue a career in the medical field and specialize. I would like to know, the experience of transfer students at Stony.
-Were you able to get classes/get into the major you declared?
-Graduate in 4 years? and do most pre-med track students receive advising for med school applications?
-Did all previously earned credits transfer successfully?
-Were you able to get housing?
-over all, was the transfer worth it?
any tips & comments would be so helpful! thank you. </p>
