The registrar's own records: 6,721 grades over 15 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 15 terms ran 2.81 to 3.77.
- A+ 306 · 4.6%

- D+ 110 · 1.6%
- D 108 · 1.6%
- D- 67 · 1.0%
- F 265 · 3.9%
- P 13 of 6,805
- NP 20 of 6,805
- I 40 of 6,805
- DR 9 of 6,805
- R 2 of 6,805
Percentages are of the 6,721 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), withdrawals (DR), and repeats (R). 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.

“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.
dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to sit in, BruinWalk has the reviews.
What comes first
dibs has not read a class page for MATH 31B, so it cannot say what comes before it.
Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.
In Winters
Ran in 4 of the last 4 Winters.
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
dibs has not read the registrar's description for this course. It reads them for general education courses only, so this says nothing about the course. Any section below links out to the registrar, where the catalog text is, and that text is also where a prerequisite the structured list does not carry would be written.
