What is inside that record
1 of those terms is a summer session, and summer sessions are counted here.
The table below splits them, and term averages across those 10 terms ran 3.02 to 3.79.

Percentages are of the 574 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.

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.

What comes first
The chain dibs can see is 5 courses long before MECH&AE 156A. Read from Fall 2026, because dibs has not read a class page for MECH&AE 156A in Winter 2026 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for MATH 3B, so the real chain can only be longer than this, never shorter.
Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.
In Winters
Ran in 4 of the last 4 Winters.
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.
