Percentages are of the 1,042 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
| Instructor | Predicted GPA | Raw | n | Terms | A range | Workload | Summer Session A 2026 |
|---|---|---|---|---|---|---|---|
| REINMAN, GLENN D reviews ↗ | 2.92 | 2.92 | 561 | 2 | 32% | average | not teaching it |
| TINE, BLAISE reviews ↗ | 3.11 | 3.11 | 247 | 2 | 40% | average | not teaching it |
| TAMIR, YUVAL reviews ↗ | 3.30 | 3.32 | 234 | 4 | 56% | 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 60 reviews 16 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
The chain dibs can see is 3 courses long before COM SCI M151B. Read from Fall 2026, because dibs has not read a class page for COM SCI M151B in Summer Session A 2026 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.
