Enroll on the registrar (opens in a new tab) Sign in to watch for an opening

Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

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: "Pre-Economics, Pre-Business Economics, Pre-Mathematics/Economics, and Sophomores and Above".

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

From the registrar enrollment limit

Enrollment is limited to sophomore/junior/senior Business Economics and Economics pre-majors.

Restrictions read 2 days ago. dibs re-reads these slowly because they rarely change; watch the section and it moves to every 6 hours.

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.

7 discussions, none open. Its waitlist is full too, at 12 of 12.

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.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

Will it still be here

dibs read 168 of the 529 hours its hourly record covers, 32%, and did not look in 361. dibs had no hourly record before 9 Sep, which is the other 556 of 1085 plotted.145 of 145 enrolled at the newest reading, 42 minutes ago, and no seats left in its discussions. Seats from 17 Aug 15:07 to 1 Oct 19:02, 145 to 145. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. dibs read 168 of the 529 hours its hourly record here covers, 32%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 361 hours dibs was keeping a record and did not reach this section. Nothing before 9 September at 19:00, where this section's record starts, has a read either way, which is 556 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

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: 42 minutes ago.

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.
