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.
What watching takes
Your setup, with any current hold shown beside the watch control.
An account
An alert needs an email address. You can browse courses and grade history without signing in.
Your year
Helps dibs interpret enrollment limits. Uncertain eligibility may still be included with a caveat.
When you can enroll
Set your appointment or acknowledge that an open seat may not be available to you yet.
A watch slot
25 per account. A lecture watch also covers its discussions. Paused watches still use a slot.
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 Registrar note
Information on the Mathematics Placement Test and Advanced Placement (AP) credit is available at https://uclamathugrad.zendesk.com/ . Seats are held for entering students who enroll through New Student Orientation sessions beginning July 2, 2026. New student restrictions will be lifted on September 15, 2026 at 8 a.m. Enrollment is contingent on taking and passing the Mathematics Diagnostic Test. There will be two MANDATORY midterm examinations from 6 to 7:50 p.m. on Monday, October 19 and Friday, November 20, 2026.
The new-student hold ended on 15 September.
Restrictions checked 5 days ago and may be outdated. Unwatched sections are rechecked less often than watched sections. Check the registrar before counting on a seat.

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.
What the work looks like
- 2 exams, 7 mentions in past reviews
- 3 quizzes, 3 mentions in past reviews
- Problem sets mentioned, no number given, 6 mentions in past reviews
Based on 818 reviews; source checked about 1 month 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
no history chance of closing before your enrollment pass.
Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

The department has not published seat counts for this class, so there is nothing to plot. dibs records when it read the class, not a count it was never given. Last read 16 Oct 16:42.
How readings and alerts work
Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.
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 2E shares one room with Lec 2 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.
