Chances of Ivy Admittance?

<p>My dream school is Columbia University and I just want someone to give me a general idea of my chances of getting in Columbia (and all the other schools on my list.)</p>

<p>I'm a junior in high school.</p>

<p>Weighted GPA: 4.54
Unweighted GPA: 3.94
Taking the ACT in two days, but all my practice tests have consistently yielded between 31 and 33.
Not taking the SAT
I'll have taken 15 honors classes and 6 AP classes, including what's on my schedule for next year as a senior.</p>

<p>Extracurricular Activities:
Dedicated piano student for ten years (won a couple city-wide competitions, and a couple state competition awards, and lots of awards from the studio I learn at)
Committed participant of an archery club (won 3rd in state, a couple more awards for tournaments, and a couple awards given by the club I shoot for.)
Monthly volunteer at the soup kitchen
Weekly volunteer at the hospital (I've volunteered about 110 hours so far)
Member of the Junior Volunteer Leadership Team at the hospital (contributed about 50 hours to the hospital through the activities the Leadership Team plans.)
Active participant of a school community service club for the third year (and will be participating again next year)
Piano player and singer for my Youth Group Worship Band
National Honor Society
National French Honor Society
National Tri-M Music Honor Society</p>

<p>And I'm not sure if this counts, but I figure skated from age four to about seventh or eighth grade and won tons of awards here too...? It's not during high school so I'm not sure if this holds any credit.</p>

<p>Over the course of my high school years, I've dedicated about 200 hours to community service.
I plan on going on a mission trip this summer; if not, I'm going to get a summer job.</p>

<p>Okay, so that's my "resume." This is my list of schools:</p>

<ol>
<li>Columbia University</li>
<li>University of California Los Angeles (UCLA)</li>
<li>Colorado College/Barnard College</li>
<li>University of Michigan</li>
<li>New York University (NYU)</li>
<li>Cornell University</li>
<li>Princeton University</li>
<li>Stanford University (actually, don't bother with this one; I know it's a huge stretch. I'm only applying because my parents want me to.)</li>
<li>University of Pennsylvania</li>
</ol>

<p>Thank you so much!</p>
