You are looking at Winter 2027. Enrollment for it has not opened, so these are the registrar's early listings. dibs holds 1,951 sections for Winter 2027, read 47 hours ago. Separately, it has finished 986 of the 3,473 courses on its own sweep list for this term. Terms nobody is enrolling in are swept one a night in rotation, so a course with nothing here may simply not have been reached yet. Back to Fall 2026

LIFESCI 30A

5 units Life Sciences

Lecture and lab.

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.

  • A+ 1,617 · 19.7%
  • A 2,531 · 30.8%
  • A- 1,129 · 13.7%
  • B+ 618 · 7.5%
  • B 643 · 7.8%
  • B- 535 · 6.5%
  • C+ 292 · 3.5%
  • C 277 · 3.4%
  • C- 161 · 2.0%
  • D+ 58 · 0.7%
  • D 114 · 1.4%
  • D- 148 · 1.8%
  • F 103 · 1.3%
  • P 2 of 8,274
  • NP 5 of 8,274
  • I 36 of 8,274
  • DR 5 of 8,274

Percentages are of the 8,226 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), and withdrawals (DR). They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication. Withdrawals are the exception to "excluded": DR is not scored, but it IS counted in the D, F or W figure above, which is reported over the letter grades plus the withdrawals. Pass/no pass and S/U outcomes are outside that figure on both sides.

“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

What comes first

dibs has not read a class page for LIFESCI 30A, so it cannot say what comes before it.

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

In Winters

Ran in 4 of the last 4 Winters.

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 Winter 2027

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 : the oldest of these 16 readings. The registrar publishes hourly and dibs reads what it can each hour, so a row can be older than that.

Final enrollment, averaged across each term's sections: between 210 and 370 a term over 9 terms, summer excluded, most recently 336 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Winter 2027

Read once so far, so there is no line to draw yet. A second reading is what turns this into a chart: courses come round within about three hours, and anything you watch every hour.
