The last nontrad free ride I heard of was an over-40 mom, for the first class at a new MD school. Makes sense to me: if I were starting a new school I'd want some mature, emotionally stable students around to abate chaos.
I think NJBMD got a free ride - she started at 45.
I have an over-40 classmate, currently M2, who got a military scholarship. I think that's a rarity - isn't the age limit 35, so that's a waiver?
Best of luck to you.
