This was well said. I think an additional tidbit of information that is helpful to think about, is that if the question following the stimulus was "which of the following, if true, would most weaken the authors argument?" and there was an option that stated, "Tigers are not mammals" that would easily be the right answer even though in the real world, we know that is not true. Everything on the LSAT is self-contained.

If I have scores from 2020, will they be included in what LSAC submits to the schools I apply to?
