Of course there is the extra stuff that you can do during you senior senior, but then again why bother. As if applying to college, filling out scholarship applications, finishing your senior project, and keeping up in your classes wasn't hard enough you can do even more. Whether you decide to contribute more to the community thought community service, or by working a job for extra cash, there are plenty of things that you can do besides just surviving your senior high school year.
The community that surrounds you isn't just a place. It's the people and the experinces that you met and gained. How you gain those experinces is up to you just as how you use them is as well.
