dibs has seen this section open 30 times since 18 August. The last time was 9 October. 6 of those were readings where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

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

  • Exams mentioned, no number given, 11 mentions in past reviews
  • Quizzes mentioned, no number given, 1 mention in past reviews
  • Problem sets mentioned, no number given, 10 mentions in past reviews

Based on 328 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.

No reading was recorded in 2 hours. dibs had no hourly record before 10 Oct, which is the other 1256 of 1426 plotted.35 of 35 enrolled at the newest reading, 34 minutes ago, and no seats left. Seats from 18 Aug 18:41 to 17 Oct 03:10, 35 to 35. Checks are not continuous monitoring. Changes between checks may be missed.

A 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: 34 minutes ago.

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.
