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 46 hours ago: "Instructor Consent".

Restrictions checked 46 hours ago and may be outdated. Seat alerts are unavailable for this course. Check the registrar.

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.

3 discussions, none open. No waitlist listed.

No discussion is open. Whatever the lecture reads, there is currently nothing here to enroll in.

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.

No reviews were listed in the BruinWalk source checked 6 days ago. Assignment details are unknown. Check the current syllabus.

Will it still be here

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

Seats over time

Nothing read since 16 Oct, 2 hours ago. Over about 2 months before that, unchanged.

Both readings say 1 seat.

Checked 168 of the 646 hours with hourly history, 26%. No reading was recorded in 478 hours. dibs had no hourly record before 19 Sep, which is the other 765 of 1411 plotted.Seats from 18 Aug 22:40 to 16 Oct 16:42, 1 to 1. Recorded enrollment counts match. Checks are not continuous monitoring. Changes between checks may be missed.

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

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.
