Grades

Read 2 hours ago. The latest refresh is overdue. Seats and instructors may have changed since. Check the registrar before enrolling.
dibs has seen this section open 4 times since 18 August. The last time was 25 September.
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
Tell dibs what you have already taken and this line will say which of these you have. Your list.
From the registrar limited until second pass
Any student attempting to save or sell a spot for another student is violating Student Conduct Code 102.23d and may be referred to the Office of the Dean of Students. Enrollment is limited to departmental majors on the priority and first enrollment passes. Any student may enroll on the second pass, space permitting.
This limit ends at an enrollment pass rather than on a date, and dibs does not hold the date second pass opens for Fall 2026, so it cannot say whether that pass has come. When it does, the registrar writes who may enroll then as “Any student may enroll on the second pass, space permitting.” So dibs cannot tell whether this class is open to you today, and it is not counting it as one you can take: your enrollment appointment on MyUCLA is what settles it.

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 read this course’s reviews and none of them say what kind of work it sets, so dibs has nothing to show rather than a guess. Read from 144 reviews 26 days ago. That is the reviewers being silent, and not a course that sets no work.
Will it still be here
high 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 1 month before that, same seat count, but the status went closed to waitlist, the waitlist went 2 of 2 to 0 of 2, and the seat count moved and came back.
4 times reopenedA 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.
Class chat
Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.
Dis 1D shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
Reading a room needs no account. Posting does, and it is free.
