Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

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

Registrar's Restrictions cell, read 3 days ago: "Computer Engineering, Com Sci, Com Sci and Engineering, Electrical Engineering, Ling of Com Sci, Undeclared Engineering Majors, or Cog Sci, C&S Bio, Math of Computation Majors or Premajors or Bioinfo, or Data Engineering Minors, and Undergraduate Students Only".

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 read 3 days ago. dibs re-reads these slowly because they rarely change; watch the section and it moves to every 6 hours.

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.

5 discussions, none open. The way in is the lecture's waitlist, at 17 of 20.

No discussion is open. 1 discussion has a waitlist with room. A place on one is not a seat: it is a queue the department may or may not clear.

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, average. 2.8 of 5 for Carey Nachenberg, where 5 is lightest. Read 30 days ago.

What the work looks like

  • Exams mentioned, no number given, said by 7 reviewers
  • 4 quizzes, said by 1 reviewer
  • 6 problem sets, said by 6 reviewers
  • 4 projects, said by 5 reviewers

Read from 46 reviews 16 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

dibs read 168 of the 494 hours its hourly record covers, 34%, and did not look in 326. dibs had no hourly record before 11 Sep, which is the other 589 of 1083 plotted.120 of 120 enrolled at the newest reading, 2 hours ago, and no seats left in its discussions. Seats from 17 Aug 15:07 to 1 Oct 17:22, 120 to 120. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. dibs read 168 of the 494 hours its hourly record here covers, 34%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 326 hours dibs was keeping a record and did not reach this section. Nothing before 11 September at 04:00, where this section's record starts, has a read either way, which is 589 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. Recorded enrollment counts match, so the line is flat across the whole window: it says when dibs looked rather than what changed. The last dot is the last time dibs read this section, moved or not, and that was 2 hours ago. It is the last thing dibs saw, not where the count is now.

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.
