Where should I go? (Undergrad)

I’ve been accepted into Northeastern, Boston University, UMASS Amherst (honors program), and Occidental College. I’m looking to major in math. I really want to be in the city, however, I am not getting any aid from bu or nu. I’m reapplying for aid with an updated form, which should give me some money, but I’m not certain how much. Here’s the total tuition and fee costs:

Northeastern: 63,000
BU: 64,000
Occidental: 54,000
UMASS Amherst: 27,000
