Congratulations on your achievements.
UT Austin is test required, so they will see your math test score. Ga Tech and several Ivies are test required as well. Which Ivies are you considering for engineering?
I agree others that you need at least one affordable highly likely school…what school is that? Do you have cost constraints? I would also add some target schools (BU and NEU are reaches.)
For the schools that offer EA, get your app in that round, don’t wait until RD.
