Which EC's should i put on the common app?

Applying to College

<p>I have a lot of EC's to put, but im not sure which will truly show my interest in math/science and show my personality to the college admissions people</p>

<p>ECs:</p>

<p>1) VP of science olympiad (4 years, first year as VP)
2) Secretary of math team (4 years, first year as secretary
3) Volunteer at Guideline tutorial (10th and 11th grade, weekends, around 300 hrs)
4) Job at Guideline Tutorial (12th grade, weekends)
5) 12 hrs volunteered at World Science Festival in NYC
6) Co-Founder of USA Biology/Chemistry/Physics Olympiad (prepares for the competition)
7) Volunteered at a Pharmacy over last summer</p>

<p>Should i put all of these on the common app? Should i combine #3 and #4? (I want to, but the limit on words isn't letting me) </p>

<p>Also, How are my EC's?</p>

<p>You have up to 12 slots available in the common app, might as well mention all of them.</p>
