Hey camisho,
don't freak out too much. I think both NJMS and RWJ will see a great deal of waitlist movement once people drop out in May. I don't know the exact figure but I think they accept on the whole about 1/3 of NJ residents who apply. According to US News, about 900 NJ residents apply and ~300 were accepted ultimately. Since ~450 people are interviewed, your chance of getting in after interview is over 60%.
BTW, I just declined their offer yesterday. So I know there is one open spot at NJMS at this point. 😉 Hopefully, you get to take that. Good luck.
