dibs
You are looking at Winter 2026. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 1,472 sections for Winter 2026, read about 1 month ago. Separately, it has finished 195 of the 3,572 courses on its current checking list for this term. Future-term coverage is incomplete, so a course with nothing here may simply not have been reached yet. Back to Fall 2026

Sections & times

Seminar.

Winter 2026: 42 sections. 36 sections are open. The oldest of these readings was about 1 month ago.

Grades

Graded S/U, so there is no average to report.

Graded S/U: 116 records over 9 terms.

In the A range

-

no letter grades in the record to count

D, F or W

-

no letter grades in the record to count

Taken pass/no pass

-

this course is graded S/U, not pass/no pass

The registrar's own records: Fall 2021 to Fall 2025. Every instructor is pooled here.

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.

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 Winters

Ran in 3 of the last 4 Winters.

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

Seminar, two to four hours; outside study, four to eight hours. Designed for graduate mechanical and aerospace engineering students. Lectures, discussions, and student presentations and projects in areas of current interest in mechanical engineering. May be repeated for credit. S/U grading.

Sections in Winter 2026

Seat counts as of : the oldest of these 42 readings. That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 10 and 13 a term over 9 terms, summer excluded, most recently 10 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Winter 2026

How each lecture has filled since dibs first saw it. This course runs 39 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.

1 hour plotted. dibs read it.0 of 10 enrolled at the newest reading, about 1 month ago, with 10 left. Seats from 27 Aug 03:05 to 27 Aug 03:06, 0 to 0. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. Every hour plotted carries a read, so a count that did not move here was checked and did not move.
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.
