I don’t think UMich would be a match for you. Your GPA ia way below their admssion range while they consider GPA to be most important. OOS admission rate is around 20%. Even double legacy won’t give you the boost you needed. Same for UT Austin considering the small percentage of OOS students admitted. Both are reaches for you, also for a couple other schools on your match list. When you claims to have double legacy at two schools, that means some are not primary legacy from undergraduate.
