“So how well did Trump do academically? Back then IQ test wasn’t a tamboo so he must’ve taken it”
This has been public for some time. Trump’s IQ is reported to be 156...genius.
I wouldn't doubt it. We have two in our family. They, too, were "mischievous" and "difficult" in school (as he is described as being before he went to military school) because they were bored to death among the other pupils (and most of the teachers) and also because they simply see more possibilities than others do when they look around.
The other interesting phenomenon is that school administrators regarded them as troublemakers and pooh-poohed the idea that they were bored out of their minds -- until they got the test results -- "Oh." Both were then skipped a grade and given other accommodations.
