You are looking at Spring 2027. Enrollment for it has not opened, so these are the registrar's early listings. dibs holds 4,154 sections for Spring 2027, read 32 hours ago. Separately, it has finished 3,438 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

MATH 33A

Linear Algebra and Applications

4 units

Lecture and discussion.

Spring 2027: 3 lectures and 18 discussions. Nothing here is open. The oldest of these readings was about 2 months ago.

Grades

3.48

Average grade awarded in MATH 33A. Not a student rating: this is what the grades were.

In the A range

66%

of the 5,123 letter grades

D, F or W

3.7%

of every letter grade awarded, plus withdrawals

Taken pass/no pass

<1%

86% of those passed

The registrar's own records: 5,123 grades over 13 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 13 terms ran 3.15 to 3.86.

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

  • A+ 305 · 6.0%
  • A 2,373 · 46.3%
  • A- 712 · 13.9%
  • B+ 494 · 9.6%
  • B 435 · 8.5%
  • B- 196 · 3.8%
  • C+ 179 · 3.5%
  • C 153 · 3.0%
  • C- 89 · 1.7%
  • D+ 52 · 1.0%
  • D 57 · 1.1%
  • D- 25 · 0.5%
  • F 53 · 1.0%
  • P 19 of 5,163
  • NP 3 of 5,163
  • S 1 of 5,163
  • U 1 of 5,163
  • I 15 of 5,163
  • DR 1 of 5,163

Percentages are of the 5,123 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), satisfactory (S), unsatisfactory (U), incompletes (I), and withdrawals (DR).

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.

Based on 676 reviews; source checked about 1 month 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 3 courses long before MATH 33A. Read from Fall 2026, because dibs has not read a class page for MATH 33A in Spring 2027 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for MATH 3B, so the real chain can only be longer than this, never shorter.

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. Enforced requisite: course 3B or 31B or 32A with grade of C- or better. Introduction to linear algebra: systems of linear equations, matrix algebra, linear independence, subspaces, bases and dimension, orthogonality, least-squares methods, determinants, eigenvalues and eigenvectors, matrix diagonalization, and symmetric matrices. P/NP or letter grading.

Final enrollment, averaged across each term's sections: between 156 and 266 a term over 10 terms, summer excluded, most recently 219 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Spring 2027

Read once so far, so there is no line to draw yet.

What turns this into a chart

A second reading is what turns this into a chart: courses come round within about three hours, and a lecture somebody is watching goes to the front of the pass. Watching is on the lecture's own page, not this one.

How readings and alerts work

Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
