It seems to me that you KNOW that she isn’t eligible for financial aid. Merit is the the only way she is getting money.
D3 schools are scrutinized as to how they give merit money. Unless she is truly merit material for Brandeis, chances are not good she will get it . Getting that kind merit money there is difficult. Not a good chance.
$80k is a lot of money to have towards law school.
My husband’s colleague would not cough up Brandeis money when he had it. Kid went to SUNY Binghamton instead. Went to law school just fine afterwards and they had the money to pay for it more comfortably
