Try to get small (1/4") colored stickers (available at office supply
stores) exactly inside the black circle!
If no black shows from under the sticker, you get 10 points each.
If black shows but it doesn't cross another line, you get 8 points.
If it crosses one line, you get 6 points.
If it crosses two lines, you get 2 points. Best possible =
360. Anything above 300 is doing great!
