You are looking at Fall 2025. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 1,964 sections for Fall 2025, read 8 days ago. Separately, it has finished 527 of the 3,473 courses on its own sweep list for this term. Terms nobody is enrolling in are swept one a night in rotation, so a course with nothing here may simply not have been reached yet. Back to Fall 2026

MATH 31A

Differential and Integral Calculus

4 units

Lecture and discussion.

Grades

Average grade awarded in MATH 31A. Not a rating: this is what the grades were.

In the A range

57%

of the 4,717 letter grades

D, F or W

of every letter grade awarded, plus withdrawals

The registrar's own records: 4,717 grades over 14 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 14 terms ran 2.40 to 3.84.

  • A+ 213 · 4.5%
  • A 1,944 · 41.2%
  • A- 542 · 11.5%
  • B+ 361 · 7.7%
  • B 484 · 10.3%
  • B- 226 · 4.8%
  • C+ 161 · 3.4%
  • C 279 · 5.9%
  • C- 130 · 2.8%
  • D+ 53 · 1.1%
  • D 91 · 1.9%
  • D- 42 · 0.9%
  • F 191 · 4.0%
  • P 18 of 4,762
  • NP 12 of 4,762
  • I 13 of 4,762
  • DR 2 of 4,762

Percentages are of the 4,717 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), and withdrawals (DR). 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.

Reviews for MATH 31A

What comes first

dibs has not read a class page for MATH 31A, 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.

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 28 readings. That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 176 and 285 a term over 10 terms, summer excluded, most recently 186 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Fall 2025
