There was a girl at school who had a very high IQ. She was good at every subject, even physical ed, and just soaked up information in every class so well, it's like she knew more than the teacher (but she was a nice girl, not an annoying know-it-all or anything, she really did know a lot).
When she left school I heard she got all A's in all her exams and went on to university to study both law and biology.
So she was smarter than the average kid, and I'd say she had a very high IQ. I used to wonder how her brain worked, as she'd just listen very attentively in every class, remembered everything the teachers taught her, and had a great passion for learning and staying focused, whatever the subject was.
As far as I know she was NT, but rather shy.
Her intelligence fascinated everyone in the class, including me. I lacked intelligence and struggled academically, even at my best subjects.
