@andee515 i would try to get the SAT and ACT as high as possible, that’s where schools will really take her seriously for merit.
If you’re in Texas now, I’m not sure how it works if you move out of state, for years 2-4. I would definitely check into residency status.
West Texas A&M, UTD, San Angelo State, UTRGV
are good Texas choices, known for money.
I would not have her take more than the 54 dual credits. More than 60 and she could be considered a transfer, could have a difficult time changing majors if she decides to later on. Not every school is impressed with large amounts of dc.
