What watching takes

Your setup, with any current hold shown beside the watch control.

An account

An alert needs an email address. You can browse courses and grade history without signing in.

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, 2 mentions in past reviews
  • Papers mentioned, no number given, 1 mention in past reviews

Based on 4 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

high risk chance of closing before your enrollment pass.

Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

All 16 readings say 40 of 40.

Checked 165 of the 1263 hours with hourly history, 13%. No reading was recorded in 1098 hours. dibs had no hourly record before 25 Aug, which is the other 151 of 1414 plotted.40 of 40 enrolled at the newest reading, 19 minutes ago, and no seats left. Seats from 18 Aug 19:40 to 16 Oct 16:42, 40 to 40. Recorded enrollment counts match. Checks are not continuous monitoring. Changes between checks may be missed.

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: 19 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.

Class chat

Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.

Dis 1A shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
