Question about community service

<p>Does the admissions committee check your community service hours?</p>

<p>I'm asking because I noticed on the common app (I'm a junior) there are blanks for "hours per week" and "weeks per year", and I don't exactly volunteer for a set amount of time each week and I don't go regularly. If I put, say, "2 hours/week" and "26 weeks/year" for the past two years that would calculate to about 150 hours, while I actually only have around 110.</p>

<p>Should I just put "varies" for both blanks? Does it really matter?</p>
