Fall 2026 enrollment is over, so there is nothing here to watch. These are the last numbers dibs read for it.

Seats
Closed.
31 of 31 enrolled.
Read 9 days ago. Fall 2026 enrollment is over, so this is a last reading, not a live count.
Its lecture reads closed (280 of 280 · 2 over enrolled): you attend both, so this seat is not one you can take while that holds. No waitlist listed.

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.
What the work looks like
- 2 exams, 9 mentions in past reviews
- 5 quizzes, 8 mentions in past reviews
- 5 problem sets, 2 mentions in past reviews
- Labs mentioned, no number given, 3 mentions in past reviews
Based on 80 reviews; source checked about 2 months ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.
Will it still be here
Not a question any more: see the notice at the top of this page.
Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

Seats over time
Filled by 1 over 2 months
1 time reopenedA dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not. Fall 2026 enrollment is over, so that is a last reading, not a live count.

How readings and alerts work
Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.
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.
Class chat
One dibs reader watches this class or has it on a plan. Nobody has posted yet.
Dis 1F shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
Reading a room needs no account. Posting does, and it is free.
