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: "Undergraduate Electrical Engineering, Computer Engineering, Computer Science & Engineering, Computational Biology, Computational and Systems Biology Majors or Data Science Engineering Minors".

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

The registrar says this two ways. Its requisites table calls the requisite above a warning, so enrollment is not blocked, and its course description for EC ENGR 113 calls the same requisite enforced. dibs follows the table and cannot tell you which one the department will act on. Read the registrar's own page.

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.

3 discussions, 1 open: Dis 1C, F 3:00pm-3:50pm. Lecture reads closed, so its 1 open discussion cannot be reached from here. There is no waitlist either, so the only way in is somebody dropping the lecture.

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. There is no waitlist either, so the only way in is somebody dropping the lecture.

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 Abeer Alwan, where 5 is lightest. Read 30 days ago.

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.

Seats over time

Nothing read since 1 Oct, 3 hours ago. Over about 2 months before that, same seat count, but the status moved and came back and the seat count moved and came back.

dibs read 168 of the 681 hours its hourly record covers, 25%, and did not look in 513. dibs had no hourly record before 3 Sep, which is the other 407 of 1088 plotted.90 of 90 enrolled at the newest reading, 3 hours ago, and no seats left in its discussions. Seats from 17 Aug 15:07 to 1 Oct 22:02, 90 to 90. dibs read 168 of the 681 hours its hourly record here covers, 25%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 513 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, and that was 3 hours ago. It is where the line stops, 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.
