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, heavy. 2.0 of 5 for Christina Kim, where 5 is lightest. Read 14 days ago.

No assignment details are available in this review summary. Based on 2 reviews; source checked 6 days ago. Missing details do not mean there are no papers or exams. Check the current syllabus.

Will it still be here

Not a question any more: see the notice at the top of this page.

Checked 168 of the 633 hours with hourly history, 27%. No reading was recorded in 465 hours. dibs had no hourly record before 20 Sep, which is the other 777 of 1410 plotted.10 of 30 enrolled at the newest reading, 3 hours ago, with 20 left. Seats from 18 Aug 20:40 to 16 Oct 13:12, 8 to 10. 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, and that was 3 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.
