>"How to spot the fake answers put there to fool you" == "how to see when an answer isn't even in the ballpark". That's a useful skill. That "context clues" thing suggests teaching students how to solve the problem in front of them, not the easy problem their mind wants to substitute for it[1].
From what this guy describes, "test prep" sounds like "educating students".
OK, sure, it does sound like educating students, IF you accept that teaching people to spot inconsistencies and trap questions in a ritualized multiple choice test is a skill that transfers to other situations. Unfortunately this is really not the case at all. It's an education in how to navigate specific public-school bureaucracy. It doesn't even teach people to navigate other shitty bureaucracies.
