Here are the differences between the 2 Schools:
RWJMS: has a high rep cuz of the RWJ Foundation but has nothing to do with it, has a large research infrastructure (Rutgers Univ, CABM, Waksman Institute, Princeton Univ), is in New Brunswick (a really nice city), no shelf exams, 10 weeks of electives during the third year (sweet!!!), some people have to go to Camden which was once america's most dangerous city, clinical rotations are done at RWJUH ( Level 1 Trauma Center), Cooper Hospital (another Level 1 Trauma center in camden), Princeton General, Jersey Shore Medical Center, Muhlenberg Med Center, NJ Cancer Center; have block exams (which is good in way to have exams at the same time), no housing provided. However you can use Rutgers gyms, student centers, libraries etc. Since all of the teaching hospitals are private, there is no scutwork. 4th year required clerkships are advanced ambulatory medicine, advanced surgery clerkship (which sux for people not interested in surgery) and neurology
NJMS: has a very large clinical infrastructure (Doctors Office Center, OSCE training site plus a rich patient diversity), is in Newark (a big gangsta city), social life includes Hoboken and NYC, students here have shelf exams which sux but no block exams thank god!, only 3 weeks of elective time during the third year, clinical rotations are done at Univ Hospital (NJs biggest Level 1 trauma center), some VA hospitals, Morristown Memorial, Hackensack Med Center, Overlook Hospital, Jersey City Med Center (for OB/GYN), St. Michaels; on campus dorms and since some of the hospitals are public there will be some scutwork. We also have lots of clinical experience first year (EMIG shadowing, SHARE family clinic, preceptorships etc) 4th year required clerkships are Emergency Medicine, PM & R and Neurology
I have been living in Newark for the past 2 years and its a quiet city as long as u stay indoors...and even if u do venture outside at night try to be at public places
