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.

Before you can enroll

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.

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

  • Quizzes mentioned, no number given, 1 mention in past reviews
  • 1 project, 1 mention in past reviews

Based on 6 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

Not a question any more: see the notice at the top of this page.

Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

Checked 143 of the 1203 hours with hourly history, 12%. No reading was recorded in 1060 hours. dibs had no hourly record before 27 Aug, which is the other 223 of 1426 plotted.26 of 40 enrolled at the newest reading, 5 hours ago, with 14 left. Seats from 18 Aug 04:30 to 16 Oct 13:32, 19 to 26. 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.

Class chat

Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.

Dis 1A shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
