Agree with Lindagaf that more information would be helpful. My son is a freshman at NU in the Explore program. It’s wonderful. Lots of flexibility at NU in terms of taking different classes, having great advisors in that program and being able to do a combined major. NU is full of bright, motivated students. He found it easy to make friends and enjoys exploring Boston with them. While you can do co-ops anywhere, most students stay in the Boston area so you could maintain your friend group. I think the NUin students also form close friendships abroad.
It is not a traditional college and there is not much Greek presence. It is expensive (looks like you did not get aid). During co-ops you will not pay tuition and your income can offset your housing costs. They are generous with giving up to 32 AP credits for scores of 4 and 5. You could become an RA for free room and board. Good luck with your decision!
