The registrar's own records: 119 grades over 2 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

No summer session is in that record.

The table below splits them.

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

  • A 119 · 100.0%

Percentages are of the 119 letter grades. Grey bars are non-letter outcomes.

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.

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.

What comes first

dibs has not read a class page for COM SCI 214 in any term it holds, so it cannot say what comes before it.

Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.

In Winters

Ran in 1 of the last 4 Winters, so it turns up in Winter sometimes rather than dependably.

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.
