Put this class on a board

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.

Before you can enroll

Registrar's Restrictions cell, read 2 days ago: "Undergraduate School of Engineering, Computational and Systems Biology, Linguistics and Computer Science, or Mathematics of Computation Majors. Premajors Are Excluded From This Population".

Tell dibs what you have already taken and this line will say which of these you have. Your list.

From the registrar

Students who enroll in upper-division courses offered by the Samueli School without completing the requisites are subject to disenrollment after the second class meeting. If necessary, consult with an OASA counselor through MyUCLA Message Center.

Restrictions checked 2 days ago and may be outdated. Unwatched sections are rechecked less often than watched sections. Check the registrar before counting on a seat.

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.

1 discussion, all open.

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, 3 mentions in past reviews
  • Problem sets mentioned, no number given, 1 mention in past reviews
  • Group works mentioned, no number given, 1 mention in past reviews

Based on 8 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

medium 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 629 hours with hourly history, 27%. No reading was recorded in 461 hours. dibs had no hourly record before 20 Sep, which is the other 782 of 1411 plotted.28 of 40 enrolled at the newest reading, 5 hours ago, with 12 left in its discussions. Seats from 18 Aug 21:40 to 16 Oct 15:52, 37 to 28. 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, and that was 5 hours ago. It is where the line stops, not where the count is now.

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.
