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, 1 mention in past reviews
- Problem sets mentioned, no number given, 1 mention in past reviews
Based on 6 reviews; source checked 6 days 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
Nothing read since 16 Oct, 8 hours ago. Over about 2 months before that, freed 26 seats.
7 times 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, and that was 8 hours ago. It is where the line stops, not where the count is now.

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.
