the registrar has this letter grade only this term
The registrar's own records: 121 grades over 4 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 4 terms ran 3.39 to 3.82.
- A+ 15 · 12.4%
- A 42 · 34.7%
- A- 33 · 27.3%
- B+ 11 · 9.1%
- B 11 · 9.1%
- B- 7 · 5.8%
- F 2 · 1.7%
- I 1 of 122
Percentages are of the 121 letter grades. Grey bars are non-letter outcomes: incompletes (I). They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

“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 MAT SCI 200, 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 4 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.
Sections in Fall 2025
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 : the oldest of these 2 readings. That term is over, so nothing has moved since.
