Average and above-average # of community service hours?

<p>ok stupid question, but like when you put on your applications your community service hours - is this over the 4 years of high school? and would that be all community service hours or do they want like
2 hours library
3 hours school clean up</p>

<p>or just all together?</p>

<p>What about community service projects my kids have done in middle school?
My kids have organized events while in MS-----Read-a-thon for tutoring program for underprivileged kids, toy drive for an orphanage in India, cultural program fundraiser for an autistic support program etc...</p>

<p>Is it a stretch to include these? I mean they spent a lot of time and effort creating and organizing these events</p>
