The registrar's own records: 309 grades over 1 term, 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+ 31 · 10.0%
- A 140 · 45.3%
- A- 35 · 11.3%
- B+ 17 · 5.5%
- B 30 · 9.7%
- B- 21 · 6.8%
- C+ 11 · 3.6%
- C 9 · 2.9%
- C- 6 · 1.9%
- F 9 · 2.9%
Percentages are of the 309 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.
By instructor
| Instructor | Predicted GPA | Raw | n | Terms | A range | Workload | Fall 2025 |
|---|---|---|---|---|---|---|---|
| SADZIK, TOMASZ MAREK reviews ↗ | 3.39 | 3.39 | 260 | 1 | 62% | - | not teaching it |
| MCDEVITT, EDWARD P reviews ↗ | 3.75 | 3.85 | 49 | 1 | 90% | - | not teaching it |
| MOLLIGO, PATRICK ANTHONY reviews ↗ | 3.75 | 3.85 | 49 | 1 | 90% | - | 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.
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.
There are no BruinWalk reviews of this course on record as of 26 days ago, so nobody has told dibs what kind of work it sets. That is dibs holding no reviews at all, and not reviewers who wrote without mentioning the work.
What comes first
The chain dibs can see is 2 courses long before ECON 105. Read from Fall 2026, because dibs has not read a class page for ECON 105 in Fall 2025 and a department can change what it requires. dibs has read a class page for every course in it.
Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.
