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.
Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

From the registrar limited early, then open
Enrollment is limited to senior Neuroscience majors and minors on the priority and first enrollment passes. Junior/senior Neuroscience majors and minors may enroll on the second pass, space permitting.
The limit applies to the earlier enrollment pass. Dibs still counts this class as one you can take, because it opens up, but on first pass it may not be yours yet. This class is also Juniors and Above, and Neuroscience Majors or Minors, which the pass does not lift.
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.
Same seat count, but the waitlist went 4 of 6 to 5 of 6 over 11 days
