The registrar's own records: 376 grades over 3 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 3 terms ran 3.80 to 3.91.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

Percentages are of the 376 letter grades. Grey bars are non-letter outcomes: passes (P), 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.
There are no BruinWalk reviews of this course on record as of 26 days ago, so nobody has told dibs what kind of work it sets. That is dibs holding no reviews at all, and not reviewers who wrote without mentioning the work.
