Ok, so a few points to consider:
1) region, area, state band/orchestra placements are great accolades, things for your letter jacket. However it is your college audition that ultimately gets you into a college of music.
3) performing at state solo & ensemble is more like the environment of a college audition.
3) the UNT education school isn't quite as exclusive as its performance school. Even if your interest is just performance, they sometimes advise to also select education as an option to increase your likelihood of acceptance.
4) typically you must first be accepted into a university academically. And then through audition you gain acceptance to the college of music. Some students at UNT 'hang around' taking regular classes, still trying to get in musically. These are usually performance folks though.
5) get with your private teacher, attain all the standard repertoire for your instrument. Start working hard and increase your lesson time each week.
6) consider taking a lesson from the professor you expect to audition with. You'll know more what to expect.
7) if you're gunning for a scholarship, fine arts scholarships help of course. But know that the big money is for academics. So get your grades up, up, up as much as you can.
7) often education majors are required to be in marching band, so don't overload your coursework in the fall season, especially first year.
Hope this is helpful.
