What is inside that record

No summer session is in that record.

The table below splits them, and term averages across those 5 terms ran 3.87 to 3.99.

Historical grades for all professors, across recorded terms. The course summary above includes all professors.

A+ 26 · 12.3%

Percentages are of the 212 letter grades. Grey bars are non-letter outcomes: incompletes (I).

How the non-letter outcomes are counted

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, A range and the workload reviewers reported for every instructor with a grade record in this course
Instructor	Predicted GPA	Raw	n	Terms	A range	Workload	Summer Session C 2026
TSIANG, MICHAEL reviews ↗	3.98	3.99	84	2	100%	light	not teaching it

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.
