While I have no doubt that Jazz has an entire life separate from what is staged on TLC (where the 'virginity losing' incident happened) I've not really seen him say anything particularly intelligent onscreen. By which I mean, something that would demonstrate critical thinking skills, or sophisticated reasoning, or even anything particularly theoretical. Standardized test scores are not all the Ivy League cares about- in fact it takes an ever-increasing range of impressive extra-curriculars because admissions is so wildly competitive. In recent years, Harvard and others have dropped SAT scores as an admission criterion because it was supposedly hindering diversity (as it advantages rich students from fancy private schools with a tutor for every subject). They do, however, definitely look for evidence of raw potential, untapped intelligence that could benefit from direction, generally, people who are fucking smart even if they haven't had the opportunity to turn that into something directly quantifiable.
Jazz can cite all the grade school grades he likes, I just don't see him demonstrate any kind of higher thinking. Not on instagram, not in the show, nothing. If anyone can think of any examples of him demonstrating any real considered thought, feel free to slap it on into the thread.
