Oh come on Ade now you're just being harsh. I understand your frustration but the digs are a bit much. I think from the posts you can see john321 is a smart guy. At least smart enough to score a meager 126. I beat that on the normal tests without even breaking a sweat. Then I tried the "Exceptional" test and found out I was a complete idiot. He's probably just like me and wants to know where he's gone wrong in trying to do the tough questions. Of course you want to check that you have the right answer before really analyzing a solution.
Ade perhaps you could try and curb this behavior in future by posting a few of the "underminded and invalidated questions" up with a link to solutions in a mock "Exceptional" test. Then people like me wouldn't have to lay awake at night wondering why I can spend a night figuring out the normal exam and score 150 and then only be able to get 2 or 3 of the "Exceptional" questions.
By the way, how long should it take to answer one of those questions?
If I can't figure a question out in a night should I realize it's over my head?
I'm sure if I took six months I could probably get 2 or 3 more, but does that mean I had a higher IQ just waiting to come out or am I just a persistent idiot?
I only ask because persistence did get me to the cannon ball solution on my own. Anyway, these will be the questions keeping me awake tonight, but at least I won't be pondering balls in a box.
