The registrar's own records: 397 grades over 5 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, and term averages across those 5 terms ran 2.81 to 3.18.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

Percentages are of the 397 letter grades. Grey bars are non-letter outcomes: passes (P) and 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
| Instructor | Predicted GPA | Raw | n | Terms | A range | Workload | Spring 2026 |
|---|---|---|---|---|---|---|---|
| MCDEVITT, EDWARD P reviews ↗ | 3.09 | 3.09 | 288 | 2 | 35% | heavy | not teaching it |
| HOPENHAYN, HUGO ANDRES reviews ↗ | 2.97 | 2.96 | 109 | 3 | 32% | heavy | 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.
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.

Read from 100 reviews 26 days ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.
What comes first
dibs has not read a class page for ECON 170 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 Springs
Ran in 2 of the last 4 Springs, so it turns up in Spring 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.
