Estimating hours per week and weeks per year

<p>I was just looking at the UC app today, and filling out a rough draft of what I'm going to write down as my extracurriculars and community service.</p>

<p>Basically I have:
~Extracurriculars~
Activity Name Hours per week Weeks per year</p>

<p>Swim team 20 45
Piano 10 50
Science Olympiad 4 38
Math Club 2 38
~Community Service~
Chinese School Helper 2 20
Key Club 1 30
Resource Center Tutor 5 30
Elementary Math Olympiad 1 20
Assistant Teacher</p>

<p>I'm not really sure about these estimates...I'm a little doubtful because on my transcript I have documented about 110 hours of community service, which is a lot less than what the totals would come out to from these estimates.</p>

<p>Do the numbers look reasonable? How strict are colleges about accuracy?
The numbers come out kind of high because I don't do the activities <em>every</em> week, but I wanted to show for how much of the year they're spread over...is that the right format or would it be better to include, say 10 weeks for key club since I only volunteer every few weeks.</p>

<p>Thanks for your input =)</p>

<p>The hours look ok to me.</p>
