I got 17 out of 20 and one of them I really should have got correct if I would have thought about it more. The other two though were helpful in learning a more exact definition of what the questions covered.
I wouldn’t call it the toughest Catholic quiz though. Envoy Magazine use to run a regular feature called inQUIZition that I think were generally much tougher. For example this one where I got only 12 of 20 right.
So what do you score?
