Analysis

Grades

2.96

Average grade awarded in MATH 131A. Not a rating: this is what the grades were. i The mean of every letter grade the registrar has published for this course, pooled across every instructor who has taught it. Not a student rating: this is what the grades were. It is not shrunk toward anything, because a course average cannot be pulled toward itself. Standard error 0.014.

The registrar's own records: 2,121 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 1.01 to 3.23.

By instructor

“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.

Reviews for MATH 131A ↗

What comes first

dibs has not read a class page for MATH 131A, 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 Falls

Ran in 5 of the last 5 Falls.

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.

You enroll in the discussion, not the lecture, so a discussion's status is the one that decides whether you get in. A lecture can read open while every discussion under it is full.

Seat counts as of 25 Aug 03:08: the oldest of these 10 readings. That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 32 and 40 a term over 13 terms, summer excluded, most recently 36 in Fall 2025. That is the shape across years, not this term, which is above.
