Seats, time, final and grades

Seats

Closed.

20 of 20 · 60 over enrolled.

Its lecture reads closed (20 of 20 · 60 over enrolled): you attend both, so this seat is not one you can take while that holds. There is no waitlist either, so the only way in is somebody dropping the lecture.

Meets

F 8:00am-8:50am

This discussion only. You also attend Lec 1.

Final

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

One exam for the whole class, Los Angeles time.

Enroll on the registrar (opens in a new tab) Sign in to watch for an opening

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 2 hours ago: "Department Consent".

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 PHYSICS 1AH 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 limited early, then open

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.

The limit stands until 15 September, and lifts then. dibs still counts this class as one you can take, but not yet. This class is also Department Consent, which that date does not lift.

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, said by 2 reviewers
  • Quizzes mentioned, no number given, said by 2 reviewers
  • 6 problem sets, said by 5 reviewers

Read from 80 reviews 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

dibs read 168 of the 538 hours its hourly record covers, 31%, and did not look in 370. dibs had no hourly record before 9 Sep, which is the other 544 of 1082 plotted.20 of 20 enrolled at the newest reading, 2 hours ago, and no seats left. Seats from 17 Aug 16:55 to 1 Oct 17:22, 20 to 20. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. dibs read 168 of the 538 hours its hourly record here covers, 31%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 370 hours dibs was keeping a record and did not reach this section. Nothing before 9 September at 08:00, where this section's record starts, has a read either way, which is 544 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. Recorded enrollment counts match, so the line is flat across the whole window: it says when dibs looked rather than what changed. The last dot is the last time dibs read this section, moved or not, and that was 2 hours ago. It is the last thing dibs saw, 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 1A shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
