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.

Workload, light. 3.5 of 5 for Daniele Bianchi, where 5 is lightest. Read 30 days ago.

dibs has read this course’s reviews and none of them say what kind of work it sets, so dibs has nothing to show rather than a guess. Read from 138 reviews about 1 month ago. That is the reviewers being silent, and not a course that sets no work.

Will it still be here

medium risk chance of closing before your enrollment pass.

dibs read 168 of the 174 hours its hourly record covers, 97%, and did not look in 6. dibs had no hourly record before 24 Sep, which is the other 911 of 1085 plotted.110 of 180 enrolled at the newest reading, 24 minutes ago, with 70 left in its discussions. Seats from 17 Aug 12:32 to 1 Oct 16:40, 122 to 110. dibs read 168 of the 174 hours its hourly record here covers, 97%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 6 hours dibs was keeping a record and did not reach this section. Nothing before 24 September at 11:00, where this section's record starts, has a read either way, which is 911 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: 24 minutes ago.

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.
