You are looking at Winter 2027.
Enrollment for it has not opened, so these are the registrar's early listings.
Dibs has read 586 of the
3,465 courses on its list for this term. Terms
nobody is enrolling in are swept one a night in rotation, so a course with nothing here
may simply not have been reached yet.

Grades
3.66
Average grade awarded in MECH&AE 281. Not a rating: this is what the
grades were.
The mean of every letter grade the registrar has published for this course, pooled across every instructor who has taught it. Not a student rating: this is what the grades were. It is not shrunk toward anything, because a course average cannot be pulled toward itself. Standard error 0.077.
In the A range
The share who got an A minus or better: A+, A or A minus, out of every letter grade awarded in this course. Pass/no pass outcomes are counted separately and are not in this figure.
69%
of the 48 letter grades
D, F or W
The share who finished with a D or an F, or withdrew. The closest thing here to a difficulty signal: it counts the people the course went badly for, which an average grade hides. Pass/no pass and S/U outcomes are counted separately and are not in this figure, so a no-pass is not in it either.
0.0%
of every letter grade awarded, plus withdrawals
Taken pass/no pass
The share who took this pass/no pass rather than for a letter grade. A high number usually means it is popular as a GE with people protecting an average. These students are excluded from the figure at the top of this block.

Every instructor is pooled here.

Percentages are of the 48 letter grades. Grey bars are non-letter outcomes.
They are excluded from the GPA entirely rather than scored, because counting a P as a
4.0 would be a fabrication.
By instructor
Predicted GPA, raw average, sample size, terms and A range for every instructor with
a grade record in this course
“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.
dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to
sit in, BruinWalk has the reviews.
dibs has not read the registrar's description for this course. It reads them for general
education courses only, so this says nothing about the course. Any section below links out
to the registrar, where the catalog text is, and that text is also where a prerequisite
the structured list does not carry would be written.
Sections in Winter 2027
Dibs has not read Winter 2027 for this course, so it cannot say whether it runs. Dibs reads the term you are enrolling in first and the rest a little at a time; the registrar's own listing is the answer until this one catches up.
