Fairly easy and fun:
I am surprisedd that Catholics did so poorly. (14 of 32 right) Obviously not CM'ers.
I took the quiz and got 27 out of 32. I would actually argue one of the questions "correct" answer as I think it is open to interpretation, but the other 4 I genuinely got wrong.
I got 29 of 32 also, messed up on Greek mythology and I think a question on Protestantism. Forgot the third.
