NEUROSC CM123
Neurobiology of Sleep
Lecture and discussion. The registrar has published a final exam time.
Fall 2026: 1 lecture and 3 discussions. Nothing here is open. The oldest of these readings was 4 hours ago.
Also listed as PHYSCI CM123 (closed, 70 of 70 · 3 over enrolled, majors only): the same class, and each department holds its own seats and its own grade history.

the registrar has this letter grade only this term
The registrar's own records: 135 grades over 4 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 4 terms ran 3.84 to 3.94.
- A+ 30 · 22.2%
- A 77 · 57.0%
- A- 18 · 13.3%
- B+ 3 · 2.2%
- B 6 · 4.4%
- B- 1 · 0.7%
- I 1 of 136
Percentages are of the 135 letter grades. Grey bars are non-letter outcomes: incompletes (I). They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

“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.
dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to sit in, BruinWalk has the reviews.
What comes first
The chain dibs can see is 6 courses long before NEUROSC CM123. This is a floor, not a deadline: dibs has not read a class page for CHEM 20B, LIFESCI 30B, MATH 3B, NEUROSC M101B, PHYSCI 111A, and PHYSCI 111B, 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 Falls
Ran in 4 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
dibs has not read the registrar's description for this course. It reads them for general education courses only, so this says nothing about the course. Any section below links out to the registrar, where the catalog text is, and that text is also where a prerequisite the structured list does not carry would be written.
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 4 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.

3 discussions, none open. The way in is the lecture's waitlist, at 5 of 6.
This limit is on the class, so it applies to all 3 discussions below.
Final enrollment, averaged across each term's sections: between 22 and 45 a term over 4 terms, summer excluded, most recently 31 in Fall 2025. That is the shape across years, not this term, which is above.
