Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

Put this class on a board

A board is one quarter you are drafting, so it needs an account to live in. Signing in brings you straight back to this page, with this class still in front of you.

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, said by 15 reviewers
  • Quizzes mentioned, no number given, said by 1 reviewer
  • Problem sets mentioned, no number given, said by 10 reviewers

Read from 68 reviews 26 days ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.

dibs read 144 of the 898 hours its hourly record covers, 16%, and did not look in 754. dibs had no hourly record before 25 Aug, which is the other 158 of 1056 plotted.39 of 40 enrolled at the newest reading, 7 hours ago, with 1 left. Seats from 18 Aug 19:40 to 1 Oct 18:32, 40 to 39. dibs read 144 of the 898 hours its hourly record here covers, 16%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 754 hours dibs was keeping a record and did not reach this section. Nothing before 25 August at 09:00, where this section's record starts, has a read either way, which is 158 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

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 7 hours ago. It is where the line stops, not where the count is now.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

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.
