I got 14/15 (93%) on this logic test I found over at the presurfer. Of course, a handful of philosophy courses and a few years of programming courses in college gave me an idea of the sorts of tactics used by logic quizzes.

Some people are QQing about the wording of the questions, but that’s the whole point of the thing- to pay attention and determine the validity of the statements given the supplied conditions. The statements need not be true, they just need to follow from the premises (which are accepted, even if not true).

I have a feeling this may trigger a(nother) debate on the definition of ‘valid’.
