CLUSTER 70B
Evolution of Cosmos and Life
This is a year, not a class
Clusters run across three quarters, fall, winter, then the spring seminar, and UCLA counts the credit on completing the yearlong cluster: four GE requirements and the Writing II requirement. Signing up for the first quarter is signing up for the year.
Dibs only reads Summer Session A 2026, so the later parts show no sections here: that is this term, not the sequence ending. What you keep if you take only part of a cluster is a question for the Cluster Program, not something these numbers answer.

The registrar's own records: 948 grades over 4 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 4 terms ran 3.60 to 3.84.

Percentages are of the 948 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.

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.

Read from 46 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 CLUSTER 70B 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.
