The registrar's own records: 1,856 grades over 14 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
1 of those terms is a summer session, and summer sessions are counted here.
The table below splits them, and term averages across those 14 terms ran 2.48 to 3.86.

Percentages are of the 1,856 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), satisfactory (S), and incompletes (I).
How the non-letter outcomes are counted
They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

Why Predicted is not the Raw average
“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.
Grade records describe outcomes. For what a course is like to take, read student reviews written on dibs below or follow the separate external review link.
Workload and assignments
Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.
dibs has read this course’s reviews and none of them say what kind of work it sets, so dibs has nothing to show rather than a guess. Read from 120 reviews about 1 month ago. That is the reviewers being silent, and not a course that sets no work.
In Springs
Ran in 4 of the last 4 Springs.
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.
