## How the grades compare

Each course has at least 100 GPA-bearing letter grades across three fall or spring terms from Spring 2023 through Spring 2026. The A share counts A grades only and pools students across sections. It excludes A− grades and non-GPA marks. Ties favor the larger sample. We used UT’s Spring 2027 print schedule to check that a course was listed.
