dibs
You are looking at Spring 2026. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 21 sections for Spring 2026, read 27 days ago. Separately, it has finished 15 of the 3,572 courses on its current checking list for this term. Future-term coverage is incomplete, so a course with nothing here may simply not have been reached yet.

Grades

3.08

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

In the A range

47%

of the 6,721 letter grades

D, F or W

8.3%

of every letter grade awarded, plus withdrawals

Taken pass/no pass

<1%

39% of those passed

The registrar's own records: 6,721 grades over 15 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 15 terms ran 2.81 to 3.77.

Historical grades for all professors, across recorded terms. The course summary above includes all professors.

  • A+ 306 · 4.6%
  • A 2,038 · 30.3%
  • A- 784 · 11.7%
  • B+ 681 · 10.1%
  • B 835 · 12.4%
  • B- 386 · 5.7%
  • C+ 389 · 5.8%
  • C 475 · 7.1%
  • C- 277 · 4.1%
  • 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).

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.

Workload and assignments

Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.

What the work looks like

  • 2 exams, said by 7 reviewers
  • 3 quizzes, said by 3 reviewers
  • Problem sets mentioned, no number given, said by 6 reviewers

Read from 818 reviews 26 days 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 2 courses long before MATH 31B. Read from Fall 2026, because dibs has not read a class page for MATH 31B in Spring 2026 and a department can change what it requires. dibs has read a class page for every course in it.

Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.

In Springs

Ran in 3 of the last 4 Springs.

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

Lecture, three hours; discussion, one hour. Requisite: course 31A with grade of C- or better. Not open for credit to students with credit for course 3B. Transcendental functions; methods and applications of integration; sequences and series. P/NP or letter grading.

Sections in Spring 2026

dibs has not read Spring 2026 for this course, so it cannot say whether it runs. dibs reads the term you are enrolling in first and the rest a little at a time; the registrar's own listing is the answer until this one catches up.
