The registrar's own records: 4,710 grades over 17 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

4 of those terms are summer sessions, and summer sessions are counted here.

The table below splits them, and term averages across those 17 terms ran 2.81 to 3.52.

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

  • A 195 · 44.0%
  • A- 15 · 3.4%
  • B+ 18 · 4.1%
  • B 129 · 29.1%
  • B- 16 · 3.6%
  • C+ 8 · 1.8%
  • C 38 · 8.6%
  • C- 8 · 1.8%
  • D+ 6 · 1.4%
  • D 1 · 0.2%
  • F 9 · 2.0%
  • P 3 of 451
  • NP 4 of 451
  • I 1 of 451

Percentages are of the 443 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.

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

Read from 534 reviews 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 PHYSICS 1A. 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/demonstration, four hours; discussion, one hour. Enforced requisites: Mathematics 31A, 31B. Enforced corequisite: Mathematics 32A. Motion, Newton laws, work, energy, linear and angular momentum, rotation, equilibrium, gravitation. P/NP or letter grading.

Sections in Fall 2026

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 10 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 134 and 187 a term over 13 terms, summer excluded, most recently 187 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Fall 2026

How each lecture has filled since dibs first saw it. This course runs 2 lectures; the legend under the chart picks one.

A dot is a reading where something moved: the seat count, the status, or the waitlist.

What a flat run means, and where a line starts

Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

Seats from 17 Aug 12:32 to 1 Oct 17:22, 152 to 188. dibs read 168 of the 537 hours its hourly record here covers, 31%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 369 hours dibs was keeping a record and did not reach this section. Nothing before 9 September at 09:00, where this section's record starts, has a read either way, which is 549 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

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.
