So, you've played computer games and every title on those pricey little boxes. You have developed great coordination between your eyes and your hands. You are king of this and master of that. (You will notice I haven't actually named any of the games. That's because I don't play them and, while I've heard of a lot of them, I haven't made a great effort to remember the names.)
OK. Eye/hand coordination is great, right? What happens when you have to add your brain to the mix? Eye/brain/hand coordination? You mean "brain" as in school? Yes, that brain.
Try this little test. Call it a game if that makes you feel better. Relax. Follow the instructions. Don't search the 'net for cheats; there aren't any. Just do it.
Let everyone know how you did. It took me five tries to score 100. That's not so bad, is it?
