The registrar's own records: 1,527 grades over 13 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 13 terms ran 3.46 to 3.77.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

- C+ 11 · 0.7%
- C 29 · 1.9%
- C- 8 · 0.5%
- D+ 1 · 0.1%
- D 3 · 0.2%
- F 2 · 0.1%
- P 3 of 1,542
- I 12 of 1,542
Percentages are of the 1,527 letter grades. Grey bars are non-letter outcomes: passes (P) 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.

Read from 60 reviews 26 days 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 2 courses long before CHEM 30AL. Read from Fall 2026, because dibs has not read a class page for CHEM 30AL in Summer Session C 2026 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for CHEM 20B and CHEM 20L, so the real chain can only be longer than this, never shorter.
Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.
From the registrar's catalog
Lecture, one hour; laboratory, six hours. Enforced requisites: courses 20B (or 20BH), 20L, and 30A (or 30AH), with grades of C- or better. Qualitative and quantitative analysis of chemical reactions and compounds, kinetics, separations, and spectroscopy. P/NP or letter grading.
