General Chemistry for Life Scientists I

Grades

3.28

Average grade awarded in CHEM 14A. Not a student rating: this is what the grades were. i The mean of every letter grade the registrar has published for this course, pooled across every instructor who has taught it. It is not shrunk toward anything, because a course average cannot be pulled toward itself. Standard error 0.007.

The registrar's own records: 7,658 grades over 14 terms, Fall 2021 to Fall 2025. 2 of those terms are summer sessions, and summer sessions are counted here. Every instructor is pooled here. The table below splits them, and term averages across those 14 terms ran 2.84 to 3.95.

By instructor

“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.

Sections in Fall 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 03 Sep 11:29: the oldest of these 14 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.
