The registrar's own records: 2,170 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 2.78 to 3.70.

Percentages are of the 2,170 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), no report (NR), 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 CHEM 30B, 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.
From the registrar's catalog
dibs has not read the registrar's description for this course. It reads them for general education courses only, so this says nothing about the course. Any section below links out to the registrar, where the catalog text is, and that text is also where a prerequisite the structured list does not carry would be written.
Sections in Summer Session A 2026
You enroll in the discussion, not the lecture, so a discussion's status is the one that decides whether you get in. A lecture can read open while every discussion under it is full.
Seat counts as of : the oldest of these 4 readings. That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 137 and 257 a term over 9 terms, summer excluded, most recently 257 in Fall 2025. That is the shape across years, not this term, which is above.
