dibs has seen this section open 35 times since 18 August. The last time was 9 October. 5 of those were readings 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.

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 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.

Your year

Helps dibs interpret enrollment limits. Uncertain eligibility may still be included with a caveat.

From the registrar Registrar note

Information on the Mathematics Placement Test and Advanced Placement (AP) credit is available at https://uclamathugrad.zendesk.com/ . Seats are held for entering students who enroll through New Student Orientation sessions beginning July 2, 2026. New student restrictions will be lifted on September 15, 2026 at 8 a.m.

The new-student hold ended on 15 September.

Restrictions read 11 hours ago.

Discussions

You enroll in the discussion, not the lecture, so the seat figure above is the sum across all of them and can read open while every discussion you could actually join is full.

6 discussions, 1 open: Dis 2B, R 1:00pm-1:50pm. Lecture reads closed, so its 1 open discussion cannot be reached from here. No waitlist listed.

These seats are real, and you cannot reach them from here. The lecture reads closed, and you enroll in the discussion but attend both, so the 1 open discussion below is out of reach while that holds. No waitlist listed.

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, 11 mentions in past reviews
  • Quizzes mentioned, no number given, 1 mention in past reviews
  • Problem sets mentioned, no number given, 10 mentions in past reviews

Based on 328 reviews; source checked 6 days 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.

Checked 168 of the 170 hours with hourly history, 99%. No reading was recorded in 2 hours. dibs had no hourly record before 10 Oct, which is the other 1255 of 1425 plotted.140 of 140 enrolled at the newest reading, 34 minutes ago, and no seats left in its discussions. Seats from 18 Aug 18:41 to 17 Oct 02:20, 121 to 140. 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: 34 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.
