School is a very strange place for the exceptionally gifted student, even moreso if neurodiverse. The student can get 100% on tests and essays with ease, yet cannot understand basic human interactions.

From the perspective of an autistic, ex-teacher who had his IQ measured as "somewhere over 170". I probably have ADHD as well, but a psychiatrist friend says diagnosis fails with people with ridiculously high IQs.

BTW, high IQ = good at solving certain kinds of problem, not a measure of the quality of a person.
