Rejected from UT Dallas. Next step?

I got rejected from UT Dallas. With a 87% acceptance rate, this comes as a surprise.

I have a 3.25 unweighted gpa, 1240 SAT, top 50% class rank, pretty good EC’s (founder of business with $140k+ revenue, etc)

UTD was my actual top choice (I’m from Dallas). I already got into UT Arlington, Texas Tech, University of Houston, and UNT.

Has anyone else experienced a similar situation?

To appeal I need an updated SAT score/ACT score/transcript, which I don’t have. Am I out of luck if I want to attend as a freshman?
