Waitlisted at TCU

Greetings! I was waitlisted at TCU after applying RD. I am from the northeast at the school was not on my radar to apply EA. After reading the TCU website I am not very hopeful for getting taken off the waitlist. I have emailed my admissions counselor stating that if I were to be taken off, TCU is where I would attend. I was wondering if anyone had experience with the waitlist at TCU? Or suggests that might enhance my chances of getting taken off? If it helps I did not submit test scores, have a 3.7uw GPA, well-rounded extracurriculars, and solid letters of rec.
