Principles and Practices of Computing

Grades

3.25

Average grade awarded in COM SCI 30. 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 0.024.

The registrar's own records: 686 grades over 9 terms, Fall 2021 to Fall 2025. 4 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 9 terms ran 3.02 to 3.61.

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 11:28: the oldest of these 3 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.

Seat risk is a prediction and seat status is what the registrar said: they are two things, and this page keeps them apart.
