The registrar's own records: 2,385 grades over 16 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 16 terms ran 3.00 to 3.72.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

- NP 5 of 2,436
- S 1 of 2,436
- U 1 of 2,436
- I 24 of 2,436
Percentages are of the 2,385 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), satisfactory (S), unsatisfactory (U), 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.
Workload and assignments
Reported assignments across instructors and terms. This term's syllabus may differ.
No assignment details are available in this review summary. Based on 350 reviews; source checked about 1 month ago. Missing details do not mean there are no papers or exams. Check the current syllabus.
What comes first
The chain dibs can see is 4 courses long before MATH 115A. Read from Fall 2026, because dibs has not read a class page for MATH 115A in Winter 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 Winters
Ran in 4 of the last 4 Winters.
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, two hours. Requisite: course 33A. Techniques of proof, abstract vector spaces, linear transformations, and matrices; determinants; inner product spaces; eigenvector theory. P/NP or letter grading.
Sections in Winter 2027
Choose an open discussion to enroll; an open lecture alone does not mean a seat is available.
Seat counts as of : the oldest of these 15 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 27 and 71 a term over 13 terms, summer excluded, most recently 37 in Fall 2025. That is the shape across years, not this term, which is above.
Seats over time in Winter 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.
