Principles of Materials Science I

Grades

3.62

Average grade awarded in MAT SCI 200. 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 0.053.

The registrar's own records: 121 grades over 4 terms, Fall 2021 to Fall 2025, summer excluded. Every instructor is pooled here. The table below splits them, and term averages across those 4 terms ran 3.39 to 3.82.

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.

Reviews for MAT SCI 200 ↗

What comes first

The chain dibs can see is 1 course long before MAT SCI 200. This is a floor, not a deadline: dibs has not read a class page for MAT SCI 120, so the real chain can only be longer than this, never shorter.

Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.

In Falls

Ran in 4 of the last 5 Falls.

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

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 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 30 Aug 19:44: the oldest of these 2 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.

  40 of 40 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.

  standing limit limited by standing: Graduate Students: restrictions read 48 hours ago, old enough that alerts on it are held

  1 discussion, all open. Lecture reads closed, so its 1 open discussion cannot be reached from here. There is no waitlist either, so the only way in is somebody dropping the lecture.

  This limit is on the class, so it applies to the discussion below.
