No Asians?
How utterly unrealistic. In the three schools that comprised the original specialized high schools in NYC (and which are still considered the best public schools in the city), the percentage of Asians has always been high. Probably about 30% in each of the schools around 1986 and approaching 60% in each school by 2006, the last year I can find statistics for. That had even led to accusations that the entrance exams were biased against blacks and hispanics. But in this show, they finally bring in a single Asian in this "elite" program, and only in the final season. That's one of the most ridiculous things about the show.
Not to mention what were they doing there anyway? No 98th or higher percentile student in NYC would go anywhere except to one of the specialized high schools. They wouldn't be in an "honors" program in a regular NYC school if they were really that smart.
