It isn't really a criticism as opposed to a "it could've been better" comment.

Like I said from the get go, I'm jaded with generic shounen (which generally requires not overthinking) and give points when they take it (the twisting of tropes, subversion of cliches, execution, style) one step further. That's one step I would've appreciated (among others).

Trick exams are age old in shounen, so having at least some people realize it and break out of the mold a little makes the series feel less generic.
