dibs has seen this section open 4 times since 18 August. The last time was 24 September. 1 of those was a reading where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

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 3 days ago: "Graduate Students".

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Restrictions checked 3 days ago and may be outdated.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.

1 discussion, 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.

Workload, average. 3.0 of 5 for Hongquan Xu, where 5 is lightest. Read 14 days ago.

What the work looks like

  • Exams mentioned, no number given, 1 mention in past reviews
  • Group works mentioned, no number given, 1 mention in past reviews

Based on 2 reviews; source checked 6 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.

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

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 821 of 1415 plotted.28 of 35 enrolled at the newest reading, 3 hours ago, and no seats left in its discussions. Seats from 18 Aug 18:40 to 16 Oct 16:43, 30 to 28. 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 3 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.
