Well, I think there is perhaps an excessively mathematical/geometric bent on the part of the quiz designer. I'm also having some trouble distinguishing between your wisdom questions and intelligence questions. Unfortunately, my wisdom is insufficient to come up with better wisdom-measuring questions.
The quiz evaluated my strength as 10 because I didn't answer any of the questions -- I have the feeling that the fact I don't know the answer to any of the questions indicates that my strength is much much less than 10.
Anyway, the quiz confirms my suspicions that my the DM running my campaign is mean. My player should have been allowed to re-roll:
Str 10, Dex 5, Con 7, Int 11, Wis 11, Cha 10
I was also very surprised to discover that I'm ideally a neutral dwarf cleric.
