The registrar's own records: 2,268 grades over 13 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 13 terms ran 2.79 to 3.97.

Percentages are of the 2,268 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), and withdrawals (DR). 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.

“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.
dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to sit in, BruinWalk has the reviews.
What comes first
dibs has not read a class page for EPS SCI 9, 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.
