Chance me for Brown ED - Senior, 4.0UW (99.43), 1540 SAT [Financial aid, astrophysics, astronomy, physics]

Need-aware schools that meet %100 of demonstrated financial aid make the majority of my list. To my knowledge, said schools keep your financial status in mind when getting accepted in a way where they might have a chance to reject you if they can’t allocate you enough funds. That makes it competetive, but does it really lower my odds to such a degree that I should refrain from said schools completely?

My initial thought was I would get at least one acceptance out of the 14-ish need blind and need aware LACs I’m applying to, which would guarantee me a full ride in the process. Is this unrealistic?
