Dinosaurs and Their Relatives

Grades

3.83

Average grade awarded in EPS SCI 17. Not a 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. Not a student rating: this is what the grades were. It is not shrunk toward anything, because a course average cannot be pulled toward itself. Standard error 0.018.

The registrar's own records: 1,132 grades over 5 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 5 terms ran 3.27 to 3.87.

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.

In Falls

Ran in 1 of the last 4 Falls, so it turns up in Fall sometimes rather than dependably.

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.

From the registrar's catalog

Lecture, three hours; laboratory, two hours; one optional field trip. Designed for nonmajors. Exploration of biology, evolution, and extinction of dinosaurs and close relatives, in context of history of biosphere. Information from paleontology, biology, and geology. P/NP or letter grading.

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 02 Sep 02:42: the oldest of these 13 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.

  274 of 274 enrolled high risk i A guess about whether this will still be here at your enrollment pass, from how full it is now and how fast classes like it have filled before. Seat risk is a prediction and seat status is what the registrar said: they are two things, and this page keeps them apart.
