Hi Balde,

This is referencing a resource called "33 common LSAT flaws," which you can find in the lesson on error in reasoning questions.

While I dont think it would be the best use of your time to memorize all 33 of them, it would probably help to familiarize yourself with the general idea of each type. Once you are able to easily recognize flaws like mistaking correlation and causation, assuming something is true of each part because it is true of the whole, or assuming that something occurs just because it was likely to occur, you can apply that understanding of why an argument is flawed. This is an important skill beyond just flawed parallel reasoning- it will help you in error questions, strengthen, weaken, strengthen with sufficient, and principle questions as well.
