What is inside that record

No summer session is in that record.

Why Predicted is not the Raw average

“Predicted” is shrunk toward the course average, which is itself shrunk toward the department, so an instructor with a handful of students sits near the course mean rather than topping the list.

Grade records describe outcomes. For what a course is like to take, read student reviews written on dibs below or follow the separate external review link.

Reviews for ARCH&UD 496

Workload and assignments

Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.

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.

In Falls

Has not run in Fall in the 4 Falls dibs holds records for, back to Spring 2022. That is 4 years of grade records rather than the course catalog, so it says what has happened and not what the department will do next. dibs has no record of it in any quarter since Spring 2024.

From the terms dibs holds, which start in Fall 2021 and exclude summer. A department can run a course in a quarter it never has before.

From the registrar's catalog

Tutorial, to be arranged. Projects initiated either by individual students or student teams and directed by faculty member. May be repeated for credit. S/U or letter grading.

Sections in Fall 2026

Seat counts as of : the oldest of these 20 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 10 and 12 a term over 3 terms, summer excluded, most recently 12 in Spring 2024. That is the shape across years, not this term, which is above.

Seats over time in Fall 2026

How each lecture has filled since dibs first saw it. This course runs 20 lectures; the legend under the chart picks one.

A dot is a reading where something moved: the seat count, the status, or the waitlist.

What a flat run means, and where a line starts

Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

dibs read 168 of the 523 hours its hourly record covers, 32%, and did not look in 355. dibs had no hourly record before 10 Sep, which is the other 542 of 1065 plotted.0 of 5 enrolled at the newest reading, 51 minutes ago, with 5 left. Seats from 18 Aug 18:41 to 2 Oct 02:32, 0 to 0. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. dibs read 168 of the 523 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 355 hours dibs was keeping a record and did not reach this section. Nothing before 10 September at 08:00, where this section's record starts, has a read either way, which is 542 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.
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.
