My son is at Urban and the school is wonderful. The current head will be retiring at the end of next year and the search for his successor is underway.
There is no instagram with college matriculation results posted publicly by student. That is counter to Urban's culture to brag about admissions. That said, they do share college matriculation data over past 5 years in a slide in the Urban Curriculum Guide, which you can find on their website.
Good luck! The school is wonderful, teachers are committed, and there are many rigorous and interesting courses offered (UAS = AP fyi).
