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: "All Biostatistics Majors".

Restrictions read 3 days ago. dibs re-reads these slowly because they rarely change, and it does not sweep graduate courses at all, so this one has no faster cadence to move to. 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.

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

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

dibs read 168 of the 853 hours its hourly record covers, 20%, and did not look in 685. dibs had no hourly record before 27 Aug, which is the other 236 of 1089 plotted.12 of 23 enrolled at the newest reading, 3 hours ago, with 11 left in its discussions. Seats from 17 Aug 15:07 to 1 Oct 23:12, 11 to 12. The line joins two or three readings, which is too few to read a trend from. dibs read 168 of the 853 hours its hourly record here covers, 20%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 685 hours dibs was keeping a record and did not reach this section. Nothing before 27 August at 11:00, where this section's record starts, has a read either way, which is 236 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, and there are only two or three of them here. The line joins the measurements; two or three readings are too few to read a trend from. The last dot is the last time dibs read this section, moved or not, and that was 3 hours ago. It is the last thing dibs saw, not where the count is now.

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.
