Chances at Yale, U of Chicago, Northwestern, Columbia

<p>Ok so all of a sudden I've gotten really nervous about the admissions process and I want some idea of my chances of getting in so id love it if you could help!
ok it's my junior year and this is what i've done in highschool:
Activities:
Speech (1)
Band (1- 5 years previous to highschool)
Tennis (5 years- 1 year on J.V team)
Key Club (1 soon to be 2year)
Yearbook ( 2 years- this year and next year)
Spanish National Honor Society(1 will be 2)
Freshman Buddy Orientation(1)
Student Aide (146 hours)
Interior Design State Qualifier
State Writing Competition </p>

<p>Summer:
People to People Student Ambassador (1)
Tennis Camp ( 2 years really intensive program)
Harvard Summer School (this year-hopefully some chances for volunteer work as well)</p>

<p>Still to come:
Darfur,Sudan project
Habitat for Humanity
Misc. Key Club Projects
Relay for Life Cancer Fundraiser
National Merit (waiting for results, strong feeling I made it)
job?</p>

<p>School:
Freshman year: honors english, advanced math, advanced spanish, honors bio
Sophomore year: honors english, advanced math, honors chem, advanced spanish, AP economics-(uncommon at my school, but they're considering changing it)
Junior: honors english, advanced math, AP spanish, honors physics, AP European History, CLC (gifted program)
Senior year: honors english, advanced math, AP Spanish, AP Bio, AP Chem, (something else, i just forgot)
4.3 gpa
(ok i kind of messed up here- i still havent taken SATs or ACTs)
but expected SAT verbal: 800
Sat math: 610-640? (on previous scale)
and ought to do well on SATIIs</p>

<p>my main concern is that i dont really have much continuity in my activities, but some medical problems and scheduling probs really forced me to pick and choose. I can always fix my test scores but the rest has to be done in a few months.</p>

<p>What is your unweighted gpa?</p>

<p>Yale and Columbia will be real long shots given no special ECs. The others you have a decent shot at would good SATs.</p>
