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.

Workload, light. 4.0 of 5 for Mark Goorsky, where 5 is lightest. Read 14 days ago.

What the work looks like

  • Exams mentioned, no number given, 3 mentions in past reviews
  • Papers mentioned, no number given, 1 mention in past reviews
  • Problem sets mentioned, no number given, 2 mentions in past reviews

Based on 6 reviews; source checked 7 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.

Checked 168 of the 591 hours with hourly history, 28%. No reading was recorded in 423 hours. dibs had no hourly record before 22 Sep, which is the other 822 of 1413 plotted.16 of 35 enrolled at the newest reading, 76 minutes ago, with 19 left. Seats from 18 Aug 18:41 to 16 Oct 14:42, 16 to 16. 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: 76 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.
