<p>I've been doing a lot of volunteering since I started high school, but I haven't really been keeping track of how many hours I've done. When I include my volunteer work on my college apps, do I need to mention the exact number of hours that I've volunteered?</p>
<p>Just say frequently/constantly over 4 years. I’d talk about it on apps though because it seems like its important to you if you didn’t even keep track of hours.</p>
