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

dibs has not read this section's restrictions yet, so alerts on it are held. Check the registrar before counting on a seat.

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.

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.

Workload, average. 2.8 of 5 for Carla Koehler, where 5 is lightest. Read 30 days ago.

What the work looks like

  • Exams mentioned, no number given, said by 6 reviewers
  • Quizzes mentioned, no number given, said by 3 reviewers
  • Papers mentioned, no number given, said by 1 reviewer
  • Problem sets mentioned, no number given, said by 3 reviewers

Read from 108 reviews 26 days 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

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

1 hour plotted. dibs read it.57 of 210 enrolled at the newest reading, about 1 month ago, with 153 left in its discussions. Seats from 25 Aug 03:05 to 25 Aug 03:06, 57 to 57. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. Every hour plotted carries a read, so a count that did not move here was checked and did not move.

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, at the end of the term. Nothing has moved since.

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 posted here.

Fall 2025 has ended, so no room can be started here now.
