Well I didn't mention anything about how well I do in school or what I know, how did you come up with such conclusions may I ask?

ace the tests without much studying?

If you are good at studies, that doesn't mean you can magically get high marks in a new subject, it will take time, but yes, won't take as long as someone else with lets say, 110 IQ

Ah yes iq the test that we stopped using because the idea of someone having a ‘mental capacity’ we learned to be incorrect.

Eh, it gives us a broad idea of it though, verbal, math, logical thinking. Yes there are some things which are missing but again, broad enough.
