Percentages are of the 1,634 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), and withdrawals (DR).
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.
Withdrawals are the exception to "excluded": DR is not scored, but it IS counted in the D, F or W figure above, which is reported over the letter grades plus the withdrawals. Pass/no pass and S/U outcomes are outside that figure on both sides.
By instructor
| Instructor | Predicted GPA | Raw | n | Terms | A range | Workload | Spring 2026 |
|---|---|---|---|---|---|---|---|
| MARGOT, JEAN-LUC reviews ↗ | 3.51 | 3.51 | 1,634 | 4 | 66% | very light | not teaching it |
| TREUDE, TINA IRENE reviews ↗ | 3.76 | 3.77 | 858 | 2 | 83% | very 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.
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.

In Springs
Has not run in Spring in the 4 Springs dibs holds records for, back to Fall 2021. That is 4 years of grade records rather than the course catalog, so it says what has happened and not what the department will do next. dibs has no record of it in any quarter since Fall 2024.
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.
From the registrar's catalog
Lecture, three hours; discussion, one hour. Origin, evolution, distribution, and future of life on Earth and in universe. Course material primarily from planetary and Earth sciences, paleontology and biology, astronomy, chemistry, and physics. P/NP or letter grading.
