Hey!
Texas Tech is a great school! I visited their AuD program over the summer.
One thing you need to be sure of, though, is being committed to being in Lubbock for the length of your program. Lubbock is really isolated ! It has everything you need, but if you like traveling to nearby cities, it might not be for you.
They are really realistic when it comes to their students. They don't really seem to want to baby step people, because their program is in the Health Sciences Center. It's really medical center focused work from what I have heard.
I don't know what other schools you applied to, but I'd take the offer !
hope this helps!
