Does anyone else feel like a lot of these can be done by just thinking them through logically and applying the rules in their heads? I feel like writing out and chaining all the conditionals would take infinitely longer when I can just do it in my head in under 2 min.

#help I don't understand how causal arguments are never valid. I went forward a few lessons and it started talking about phenomena and the arguments, but how are they invalid? Also, couldn't causal logic be transformed to an if, then argument? #feedback

how pertinent is understanding all of this to doing well on the actual test
