Scoring: Count up your points.
0 - 2 : You seem to be lost in "Ozone Oblivion." Spend some more time browsing the site to sharpen those ozone skills.
How'd you do?
3 - 4 : Not bad. You could use a little brushing up, though. A haze of "Smog Fog" could be hiding the facts from you.
5 - 6 : Nice job. You are well on your way to becoming a "Pollutant Punisher." You will be a big help in blocking ground-level ozone.
7 : A perfect score! Congratulations! You have earned the title: "Ozone Overthrower!"
