snowman24,
I am a college freshman right now at in Marquette's seven year program..and just like you, I am from New Jersey.
I know that you really want to stay close to home--I was in the same boat as you. But think about it--what's more important..your career? or where you'll be living? To be honest, with your stats, getting into the UMDNJ program may be slightly difficult. My SAT scores were well above 1350 and I was in the top one percent of my high school class...and I was only accepted into Marquette's program. Remember that these are the minimum requirements. The few students who are eventually accepted are usually much better.
Don't be afraid to come to Marquette or try a new place. All you need at Marquette to have guaranteed acceptance to the dental school is to maintain a 3.5 GPA...which isn't bad at all. However, if you absolutely want to stay on the east coast, there are plenty of 7 year programs that could apply to (although it is more difficult to be accepted to these). NYU, Boston U, UConn, Tufts, UPenn, etc etc..there are so many schools with similar programs. If you do end up applying to all these, and Marquette is the only one you're accepted to...don't be afraid to try go somewhere far for your career's sake!
Hope that helps. =)
