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 days ago: "Graduate Students".

Tell dibs what you have already taken and this line will say which of these you have. Your list.

From the registrar

For Statistics 10 through 186, enrolling on the wait list does not guarantee enrollment in the course. A place on the wait list only offers a chance to add the course if enrolled students drop the course.

Restrictions checked 2 days ago and may be outdated. Seat alerts are unavailable for this course. Check the registrar.

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.

Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

Seats over time

Nothing read since 16 Oct, 2 hours ago. Over about 2 months before that, same seat count, but the status went closed to closed by the department, the cap stopped being published, and the seat count moved and came back.

Checked 168 of the 594 hours with hourly history, 28%. No reading was recorded in 426 hours. dibs had no hourly record before 21 Sep, which is the other 819 of 1413 plotted.20 of 20 enrolled at the newest reading, 2 hours ago, and no seats left. Seats from 18 Aug 20:40 to 16 Oct 16:43, 20 to 20. Checks are not continuous monitoring. Changes between checks may be missed.

A dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not, and that was 2 hours ago. It is where the line stops, 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.
