Read 3 days ago.
Read 2 hours ago. The latest refresh is overdue. Seats and instructors may have changed since. Check the registrar before enrolling.
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 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 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, 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.
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.

Seats over time
Nothing read since 1 Oct, 2 hours ago. Over about 2 months before that, freed 5 seats.
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 2 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.
