The registrar's own records: 85 grades over 4 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
No summer session is in that record.
The table below splits them, and term averages across those 4 terms ran 3.77 to 3.91.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.
- A+ 5 · 5.9%
- A 54 · 63.5%
- A- 14 · 16.5%
- B+ 10 · 11.8%
- B 1 · 1.2%
- B- 1 · 1.2%
Percentages are of the 85 letter grades. Grey bars are non-letter outcomes.
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.
By instructor

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 not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.
In Falls
Ran in 3 of the last 5 Falls, so it turns up in Fall sometimes rather than dependably.
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
