My FA Situation is Bound to Change.... What does this mean for my Scholarships?

Hey, guys. I applied to NYU with a 36 ACT and a 4.0 UW and I received a 40K CAS Scholarship and an offer of 3,000 in Work Study and rest in loans (COA 71K)… With this offer, I can afford NYU

My EFC this year was 20.5K, but with my brother graduating next year I know it will raise. He goes to a state University and we are only paying maybe 8K a year.

How is this going to affect my NYU CAS Scholarship (which I assume is given on a combination of need and merit)? I don’t want to spend 28K dollars for my freshman year, and then have to transfer out because I can not afford it for future years.
