Put this class on a board
A board is one quarter you are drafting, so it needs an account to live in. Signing in brings you straight back to this page, with this class still in front of you.
Before you can enroll
Restriction details are unavailable, so alerts are paused. Check the registrar before counting on a seat.
Discussions
You enroll in the discussion, not the lecture, so the seat figure above is the sum across all of them and 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.
What the work looks like
- 2 exams, 7 mentions in past reviews
- 3 quizzes, 3 mentions in past reviews
- Problem sets mentioned, no number given, 6 mentions in past reviews
Based on 818 reviews; source checked about 1 month 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
Unchanged over 3 minutes
Both readings say 203 of 210.
A dot is a reading. Recorded enrollment counts match, so the line is flat across the whole window: it says when dibs looked rather than what changed. The last dot is the last time dibs read this section, moved or not, at the end of the term. Nothing has moved since.

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
Nobody on dibs watches this class or has it on a plan yet. Nobody posted here.
Fall 2025 has ended, so no room can be started here now.
