Your private school counselor will be a much better guide for chancing you on your school list as they have context that we don’t.
I agree with the other posts who recommend removing the out of state publics from your list because of cost and substituting some of the private schools already mentioned. (And for others reading, U Mass and Purdue should be considered reaches for all out of state CS students as the major has become very very competitive).
Be sure that your guidance counselor mentions the death in the family in their letter of recommendation.
Good luck and congrats on already having an acceptance! UTD for CS is a great back up!
