dibs
You are looking at Fall 2025. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 1,964 sections for Fall 2025, read about 1 month ago. Separately, it has finished 527 of the 3,572 courses on its current checking list for this term. Future-term coverage is incomplete, so a course with nothing here may simply not have been reached yet. Back to Fall 2026

the registrar has this letter grade only this term

The registrar's own records: 1,371 grades over 15 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

2 of those terms are summer sessions, and summer sessions are counted here.

The table below splits them, and term averages across those 15 terms ran 3.55 to 3.99.

Historical grades for all professors, across recorded terms. The course summary above includes all professors.

  • A+ 99 · 7.2%
  • A 752 · 54.9%
  • A- 379 · 27.6%
  • B+ 88 · 6.4%
  • B 40 · 2.9%
  • B- 6 · 0.4%
  • C 4 · 0.3%
  • D 3 · 0.2%
  • P 1 of 1,373
  • I 1 of 1,373

Percentages are of the 1,371 letter grades. Grey bars are non-letter outcomes: passes (P) and incompletes (I).

How the non-letter outcomes are counted

They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

Why Predicted is not the Raw average

“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.

Workload and assignments

Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

What comes first

The chain dibs can see is 2 courses long before EE BIOL 100L. Read from Fall 2026, because dibs has not read a class page for EE BIOL 100L in Fall 2025 and a department can change what it requires. dibs has read a class page for every course in it.

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

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

Laboratory, four hours. Requisites: course 100 (may be taken concurrently), Life Sciences 1 or 7B. Introduction to research methods in ecology and behavior, resulting in independent research proposals and to gain understanding of scientific method, critical evaluation of research papers, and development of scientific writing skills. Involves work outside and off-campus meetings. To apply this course to the Biology upper-division major laboratory requirement, the corresponding lecture course must be completed with a passing grade. Letter grading.

Sections in Fall 2025

Seat counts as of : the oldest of these 6 readings. That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 14 and 18 a term over 13 terms, summer excluded, most recently 16 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Fall 2025

How each lecture has filled since dibs first saw it. This course runs 6 lectures; the legend under the chart picks one.

A dot is a reading where something moved: the seat count, the status, or the waitlist.

What a flat run means, and where a line starts

Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
