I saw that 29% figure too, but it’s from six years ago when there were fewer applicants. From their website, it looks less than 10% enrolled. Doesn’t say how many total were admitted. I assume some who were admitted ended up at other schools. https://macaulay.cuny.edu/wp-content/uploads/2017/01/quick-facts.pdf
That 10% number was for class of 2020

3.93 GPA, 1430 SAT, good extracurriculars, great recs. I got into 2 other schools in NY so I am not so upset just sort of surprised.
