Also listed as PHYSCI CM223 (closed by the department): the same class, and each department holds its own seats and its own grade history.
Dibs does not read seat counts for graduate courses, so it cannot tell you when this one opens. Check the registrar.
Open on the registrar (opens in a new tab)- Status
- Closed by the department
- Restrictions read 19 hours ago.
- Enrolled in lecture
- 1 enrolled
- The department published this count and no capacity, so there is no share to fill.
- Dibs does not track seats for graduate courses. UCLA's Schedule of Classes limits how much Dibs may read each hour, and covering the whole catalog would mean covering none of it well, so undergraduate courses get the requests. This figure is whatever was last read on 29 August and is not being kept up to date. Check the registrar.
- Waitlist
- No waitlist
- Seat risk
- Not computed: dibs does not read seat counts for graduate courses, so the fullness half of this would be a guess on a number it is not keeping up to date.
Discussions: this is what you enroll in
Enrollment at UCLA acts on the discussion, not the lecture. The lecture's seat count above is the sum across all of them, so it can read open while every discussion you could actually join is full.

What students say
Dibs measures outcomes: grades, seats, how fast it fills. For what the class is actually like to sit in, BruinWalk has the reviews.
Enrollment over time
A dot is a reading where something moved: the seat count, the status, or the waitlist. The last one is the most recent sweep, moved or not. The line holds flat between dots because that is what the readings say: it did not drift, it held and then jumped. The ticks along the bottom are the hours Dibs recorded reading this section, which is how a flat run says "checked, unchanged" rather than "nobody looked". It only keeps those from 25 August, so the ruler is shorter than the line for now. Both start when Dibs did rather than reaching back before it existed.
