Before you can enroll

Registrar's Restrictions cell, read 7 hours ago: "Undergraduate Students Only".

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 read 7 hours ago.

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.

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: 55 minutes ago.

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.
