Mathematics for Life Scientists

Grades

3.40

Average grade awarded in LIFESCI 30A. 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 0.007.

The registrar's own records: 8,226 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 2.88 to 3.74.

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 LIFESCI 30A ↗

In Falls

Ran in 5 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

Lecture, three hours; laboratory, two hours. Preparation: three years of high school mathematics (to algebra II), some basic familiarity with computers. Mathematical modeling as tool for understanding dynamics of biological systems. Fundamental concepts of single-variable calculus and development of single- and multi-variable differential equation models of dynamical processes in ecology, physiology, and other subjects in which quantities change with time. Use of computer programming for problem solving, plotting, and dynamical simulation in laboratory. 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 66 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.
