dibs reads this section's seats hourly, like everything else, but it does not send alerts for graduate courses yet.

Seats, time, final and grades

Seats

Open, 39 seats left.

21 of 49 enrolled, lecture and all discussions summed.

Subtract those two and the lecture has 28 places in it. The 39 seats above are what is open in the discussions, and you enroll in a discussion, so that is the figure that decides whether you get in.

Meets

TR 12:00pm-1:50pm

Lecture only. You also attend a discussion, listed below.

Final

Wed 9 Dec, 3:00pm to 6:00pm

One exam for the whole class, Los Angeles time.

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

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 4 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.

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.

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.

dibs read 168 of the 687 hours its hourly record covers, 24%, and did not look in 519. dibs had no hourly record before 3 Sep, which is the other 407 of 1094 plotted.21 of 49 enrolled at the newest reading, 18 minutes ago, with 39 left in its discussions. Seats from 17 Aug 15:07 to 2 Oct 04:12, 11 to 21. dibs read 168 of the 687 hours its hourly record here covers, 24%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 519 hours dibs was keeping a record and did not reach this section. Nothing before 3 September at 14:00, where this section's record starts, has a read either way, which is 407 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: 18 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.
