I'm really lousy at Latin, but then I've only been to a handful of Tridentine Masses, and we all know how much Latin there is in the Novus Ordo, don't we?
Here are two Latin quizzes. Don't worry, there's only ten questions on each, so no need to brush up first. I only scored 5/10 on the first and 6/10 on the second. Anyone who scores worse than me will be be subjected to the medieval penances. All ten of them.
