Walnut Hills had about 25 kids who were NMSF this year. NMSF is approximately equivalent to top 16,000 on PSAT. There were 3,741 36 composites last year. Based on those numbers, you’d expect somewhere in the neighborhood of 5 or 6 36s each year. 17 is a bit out of the ordinary, but certainly not unbelievable for a school where a significant number of kids regularly score very highly on standardized testing.
