The registrar's own records: 5,123 grades over 13 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 13 terms ran 3.15 to 3.86.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

- P 19 of 5,163
- NP 3 of 5,163
- S 1 of 5,163
- U 1 of 5,163
- I 15 of 5,163
- DR 1 of 5,163
Percentages are of the 5,123 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), satisfactory (S), unsatisfactory (U), 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.

Based on 676 reviews; source checked 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 3 courses long before MATH 33A. Read from Fall 2026, because dibs has not read a class page for MATH 33A in Summer Session A 2026 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for MATH 3B, 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, three hours; discussion, one hour. Enforced requisite: course 3B or 31B or 32A with grade of C- or better. Introduction to linear algebra: systems of linear equations, matrix algebra, linear independence, subspaces, bases and dimension, orthogonality, least-squares methods, determinants, eigenvalues and eigenvectors, matrix diagonalization, and symmetric matrices. P/NP or letter grading.
