Oh, no-no, nothing of the sort. Our older’s high school CS research mentor (they ended up publishing a paper together) did his undergrad in Math at UChicago. Similar to you, he shared fond memories of the place.
It’s just that there is, indeed, admissions calculus (or, rather, arithmetic) on that board. I know it’s hard to make out. I’ll take the first stab:
"Keep Stats
#ADM
#MINORITY = ?
#FEMALE
ADMIT = 48
+1 | 49
48 adm
#minority = 3?
#female = 21"
