Seats

Cancelled.

The department has not published seat counts for this class.

Its lecture reads waitlist (30 of 30 · 5 over enrolled): you attend both, so this seat is not one you can take while that holds. The way in is the lecture's waitlist, at 1 of 5.

Meets

This discussion only. You also attend Lec 1.

Final

None on the page dibs read

No exam time on the page dibs read. That is not the registrar saying there is no final.

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

Not a question any more: see the notice at the top of this page.

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 25 Sep 04:12.

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 1B shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
