Read 40 minutes ago. This is a recent reading, not a live seat count.

dibs has seen this section open 5 times since 18 August. The last time was 30 September. 1 of those was a reading where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

From the registrar

Information on the Mathematics Diagnostic Test and Advanced Placement (AP) credit is available at https://uclamathugrad.zendesk.com/ .

Restrictions read 14 days ago. dibs re-reads these slowly because they rarely change, and it does not sweep graduate courses at all, so this one has no faster cadence to move to. Check the registrar.

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.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

Will it still be here

dibs read 118 of the 848 hours its hourly record covers, 14%, and did not look in 730. dibs had no hourly record before 27 Aug, which is the other 208 of 1056 plotted.35 of 38 enrolled at the newest reading, 40 minutes ago, with 3 left. Seats from 18 Aug 19:40 to 1 Oct 18:32, 19 to 35. dibs read 118 of the 848 hours its hourly record here covers, 14%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 730 hours dibs was keeping a record and did not reach this section. Nothing before 27 August at 11:00, where this section's record starts, has a read either way, which is 208 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: 40 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.
