The registrar's own records: Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them.

- U 1 of 296
- I 1 of 296
Percentages are of the 0 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), satisfactory (S), unsatisfactory (U), and incompletes (I). They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

“Predicted” is shrunk toward the course average, which is itself shrunk toward the department, so an instructor with a handful of students sits near the course mean rather than topping the list.
dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to sit in, BruinWalk has the reviews.

Ran in 4 of the last 4 Falls.
From the terms dibs holds, which start in Fall 2021 and exclude summer. A department can run a course in a quarter it never has before.
From the registrar's catalog
dibs has not read the registrar's description for this course. It reads them for general education courses only, so this says nothing about the course. Any section below links out to the registrar, where the catalog text is, and that text is also where a prerequisite the structured list does not carry would be written.
Sections in Fall 2026
Seat counts as of . The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.
