As with many to most very competitive public universities, kids, parents, less clued in guidance counselors, etc may ignore applicants compete against other applicants, e.g., 1. identical grades at higher vs lower level college prep curriculum levels within the same high schools are not equal; 2. Kids from more vs less competetive schools; 3. heavy AP vs less to no AP; 4. Extracurricular leadership vs little to no participation; 5. Schools with many vs advantage to those with few UConn applicants (in-state separate from out-of-state/country); 6. Kids in socioeconomically advantaged vs disadvantaged backgrounds, locations, etc (a la UConnRock’s Penn reference) 7. Kids applying to engineering, nursing, business & other tougher schools/majors vs traditionally easier schools/majors such as Coms, Ag, some liberal arts, etc; 8. Other related considerations at UConn, MD, IU, Michigan, UVA, UT, Cal, UW, etc
Bottom line: it’s highly likely applicant analyses are far more involved or sophisticated than may initially meet the eyes, form anecdotal opinions, etc
I don't disagree with anything you said It's still surprising how things have changed. I went to a high school that 15+ kids in a class got into UConn when i graduated. Now, kids who had the same stats as my friends who got into UConn aren't getting in now.
