<p>What is a good number to have? I have 9 atm, with some being more involved than others (though these are the activities I enjoyed the most). I can think of a couple more things to include, but is it worth it at this point? Like, I was technically in a club but it only met three times. I would also help a friend with math, but I was not paid or anything and it would not be for more than 10 hours total.</p>
<p>I believe the application says something like list your “principle” activities, so with 9 involved activities, that sounds like enough. Actually, it sounds like a lot 
Good luck.</p>
<p>Do not list the club or the 10 hours of help you gave … it would look like you’re trying to stretch the activities, or that you only did those activities to fill up your resume. Stick to the significant ones that you didn’t for multiple years, especially those were you took on a broader and broader role over time.</p>
