What does he do for fun?

There is no denying that he is an over achiever.  Is he the  captain/president  of these clubs at the same time/same term?  If that is the case, it can be easily construed in a not so positive light.  Some schools purposefully limit how many leadership positions a student can hold,  to prevent monopoly, and give other students a chance to shine.  In the Common App form, there are only  6 or so lines reserved for EC activities.   When it  is time to apply, it  pays to selectively limit the activities in writing  instead of listing all of them.
