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 about 2 months ago. Separately, it has finished 527 of the 3,617 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. Back to Fall 2026

The registrar's own records: 2,432 grades over 15 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

2 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 2.80 to 3.80.

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

  • A+ 160 · 6.6%
  • A 798 · 32.8%
  • A- 326 · 13.4%
  • B+ 206 · 8.5%
  • B 308 · 12.7%
  • B- 150 · 6.2%
  • C+ 121 · 5.0%
  • C 143 · 5.9%
  • C- 99 · 4.1%
  • D+ 25 · 1.0%
  • D 35 · 1.4%
  • D- 12 · 0.5%
  • F 49 · 2.0%
  • P 6 of 2,466
  • NP 5 of 2,466
  • I 23 of 2,466

Percentages are of the 2,432 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), and incompletes (I).

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.

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.

What comes first

The chain dibs can see is 4 courses long before MATH 170E. Read from Fall 2026, because dibs has not read a class page for MATH 170E in Fall 2025 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 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

Lecture, three hours; discussion, one hour. Requisite: course 32B. Highly recommended: course 61 or 70. Not open to students with credit for course 170A, Electrical and Computer Engineering 131A, or Statistics 100A. Introduction to probability theory with emphasis on topics relevant to applications. Topics include discrete (binomial, Poisson, etc.) and continuous (exponential, gamma, chi-square, normal) distributions, bivariate distributions, distributions of functions of random variables (including moment generating functions and central limit theorem). P/NP or letter grading.
