The reason why I am asking is to gather more input from you for possible merit $.
You indicated that you earn $360.000 per year and have close to $2 million in non- retirement assets… and you expect a discount. You will not get any type of need based discount. Your twins may get merit $ if they apply smartly…or…maybe… if they have major accomplishments outside of academics (hyper competitive scholarships want to see this). I do think there is a chance at GT. Anyway, I have said all there is to say.
Good luck!
