How many ECs should I list on the Common app??

<p>Right now I have 10 ECs, and I'm kind of becoming paranoid that I have too many...</p>

<p>Soccer (4 years)
Tennis (4 years)
iPhone Application Design Course & Maintenance (2 years - but I have a leadership position)
Pascack-Volunteers (2 years - Founder/Co-President)
Investment Club (3 years)
Math League (4 years - some awards)
Debate (4 years - some awards)
Peer Leaders (2 years -only open to juniors and seniors)
Community Blood Services (blood bank) Telerecruiter and donor room assistant (3 years - this is where I racked up my community service hours)
UNICEF Club (2 years - but I have a leadership position)</p>

<p>Is this too much? Should I remove some of these activities? The first 2 activities that I would be okay with taking off, with be Math League/Investment Club (although I wouldn't really want to do this because I'm majoring in Finance) or UNICEF Club/Investment Club (it was pretty hard for me to become VP of UNICEF club, and it was also just started when I became a junior). </p>

<p>How many of you are including 10 ECs?</p>
