I scored a 31 and quite honestly I feel that is a little high.
Some of the questions, the answer has been yes for so long that it just seems normal for me. So I think I've built up a bit more tolerance than the quiz allows in the score.
I think I took this quiz before or maybe one much like it on some other site. I scored 36 just now. Two 36 scorers in a row....interesting coincidence.
