The registrar's own records: 7,758 grades over 16 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
3 of those terms are summer sessions, and summer sessions are counted here.
The table below splits them, and term averages across those 16 terms ran 2.70 to 3.62.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

- D 151 · 1.9%
- D- 6 · 0.1%
- F 76 · 1.0%
- P 28 of 7,818
- NP 7 of 7,818
- I 23 of 7,818
- DR 2 of 7,818
Percentages are of the 7,758 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), and withdrawals (DR).
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.
Withdrawals are the exception to "excluded": DR is not scored, but it IS counted in the D, F or W figure above, which is reported over the letter grades plus the withdrawals. Pass/no pass and S/U outcomes are outside that figure on both sides.

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.
What the work looks like
- 2 exams, said by 6 reviewers
- 4 quizzes, said by 3 reviewers
- 5 problem sets, said by 4 reviewers
Read from 152 reviews about 1 month ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.
What comes first
The chain dibs can see is 1 course long before CHEM 14B. Read from Fall 2026, because dibs has not read a class page for CHEM 14B in Spring 2026 and a department can change what it requires. dibs has read a class page for every course in it.
Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.
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.
