Waitlist Wonder!

<p>Okay, so this is my first post on the forum, possibly to relieve some frustration, but mostly to see what other people have to say. Don't judge my academic worth from the quality of my writing/grammar right now, as I'm typing on a broken Iphone:) Ill start with my credentials.
I'm from Minnesota, I am top 15% of my graduating class. I have a 3.96 GPA. I scored a 30 on the ACT. Extracurriculars are nice and beefy ( student council, 3 varsity sports, math team, etc).
I'm no Shakespeare but I could put together a solid essay for my applications....
I take our schools advanced IB courses in that we don't offer AP.
Recently I received my admissions decisions from many colleges and for the small less challenging schools was very pleased. I did get four peculiar white envelopes from colleges where I felt qualified (if not possibly overqualified!!) The colleges were Wake Forest U, Colorado college, Boston college, and Texas Christian University. Wait list.
The school I'm writing mostly about is TCU. Looking at average scores and whatnot, I seem to be a great candidate for admission there! Does anybody have any insight as to why a fellow like myself would not be swept into the admitted pool at TCU?</p>

<p>Thank you! :)</p>

<p>Undecided/biology major btw.</p>

<p>TCU ACT composite says 24-29?</p>
