How we got this

Class names, credit hours and descriptions come from UT’s Integrative Biology catalog page, checked October 27, 2026.

Grades come from UT’s grade dashboard. We combine every letter grade since Summer 2011, so bigger classes count for more. A’s counts A grades; A− has its own bar on each class page. How the averages are calculated.
