Community service means service to the community. Go help unload trucks at a food bank for the needy. work at a soup kitchen. You just might learn why you should strive to be successful. How about organizing a bake sale with the proceeds going to the food bank? Maybe you should give back to the community, who are paying for your education. If you are required to do two, why not over-achieve and do more than two? How about highway clean up? That's what county inmates do for community service.
For one, you can help clean up something around the school. That's a sure way to get some community service in. Try wiping up bleachers or cafeteria tables. Another thing you can do is help another teacher out with any paperwork they might have. Often, they have paperwork that needs to go somewhere else in the building or papers that need copying or printing. You can help a teacher that way.
