Wow, thanks so much for this detailed explanation . I get it now.
By doing older games over and over again, I’m seeing things I never saw (inferences ) during the first take. Also, I’ve noticed that when a rule is expressed in formal logic, that many of the questions indirectly ask for a translation of the FL. Also, I find that I have trouble envisioning a diagram when a game involves subsets.
Is this a good approach to take? ie. going over previous games again (in addition to your drills.)
I know that I’m improving, although it still feels like I’m climbing a mountain.
