The registrar's own records: 6,514 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 3.34 to 3.73.

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

  • A+ 592 · 12.8%
  • A 1,716 · 37.1%
  • A- 723 · 15.6%
  • B+ 484 · 10.5%

  • B- 223 · 4.8%

  • D+ 17 · 0.4%
  • D 13 · 0.3%
  • D- 10 · 0.2%
  • F 28 · 0.6%
  • P 3 of 4,646
  • NP 2 of 4,646
  • I 12 of 4,646

Percentages are of the 4,629 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.

Reviews for PSYCH 100B

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.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

What comes first

The chain dibs can see is 1 course long before PSYCH 100B. 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, two hours; laboratory, two hours. Enforced requisite: course 10, with grade of C or better. Introduction to research methods and critical analysis in psychology. Lecture and laboratory topics include experimental and nonexperimental research methods, statistical design and analysis as applied to a broad range of basic and applied research issues. May be repeated once for credit. 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 21 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 311 and 436 a term over 12 terms, summer excluded, most recently 416 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.

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 18 Aug 18:40 to 2 Oct 06:32, 420 to 419. dibs read 168 of the 523 hours its hourly record here covers, 32%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 355 hours dibs was keeping a record and did not reach this section. Nothing before 10 September at 12:00, where this section's record starts, has a read either way, which is 546 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.
