NE is a fairly expensive school like many private schools in New England. The COA can get close to $70K per year (who’s counting small 1,000’s). If the NPC produced $30k for you then you are receiving some nice merit aid. I think you mentioned they are giving you $31K grant per year. that is fantastic. You also need to remember that NE has a fantastic co-op program that allows you to work full time in college. You can make most of this $30K during the co-op period. You then basically have a guaranteed job when you graduate.
It sounds like you have a great opportunity. Good luck.
