Well, Boston is the main reason. My husband and I went to undergrad in Boston, and I lived there for several years after. We would like to live and work in the Boston area after I graduate, and I figure I'm more likely to get a job in the Boston area with a Northeastern degree. I'm not sold on the rankings...Rutgers is ranked only slightly higher than Northeastern. Plus the co-ops: I really like the idea of the practical experience the co-op offers and the fact that there are more opportunities for such experience than the normal summer associate positions.
The PI program at Rutgers is what will make me choose them over the other schools I've been accepted to, should Northeastern not work out. I'd like to at least have the option of choosing Northeastern over Rutgers, but the cost difference between the two schools may sway me toward Rutgers regardless.
The bottomline: I've decided not to decide until I hear from Northeastern.
