You are looking at Winter 2026.
That term is over, so these are last term's numbers rather than seats you can take.
Dibs has read 195 of the
3,464 courses on its list for this term. Terms
nobody is enrolling in are swept one a night in rotation, so a course with nothing here
may simply not have been reached yet.

Teaching in Winter 2026
Nothing in Winter 2026. This instructor has no sections on the schedule dibs has read, which is not the same as never teaching the course again: the record below is from earlier terms.
Grade record by course

|---|---|---|---|---|---|
| CLUSTER 70A Evolution of Cosmos and Life | 3.72 | 3.72 | 555 | 2 | 81% |

“Predicted” is shrunk toward the course average, which is itself shrunk toward the department, so a course taught once to twelve students sits near the course mean rather than at whatever those twelve happened to get.
