the registrar has this letter grade only this term
The registrar's own records: 734 grades over 11 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
4 of those terms are summer sessions, and summer sessions are counted here.
The table below splits them, and term averages across those 11 terms ran 3.43 to 4.00.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.
- A+ 137 · 18.7%
- A 473 · 64.4%
- A- 54 · 7.4%
- B+ 21 · 2.9%
- B 21 · 2.9%
- B- 8 · 1.1%
- C+ 1 · 0.1%
- C 4 · 0.5%
- C- 3 · 0.4%
- D 2 · 0.3%
- D- 1 · 0.1%
- F 9 · 1.2%
- I 1 of 736
- DR 1 of 736
Percentages are of the 734 letter grades. Grey bars are non-letter outcomes: incompletes (I) and withdrawals (DR).
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.
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.
By instructor
| Instructor | Predicted GPA | Raw | n | Terms | A range | Workload | Spring 2027 |
|---|---|---|---|---|---|---|---|
| DAVERSA, DAVID reviews ↗ | 3.89 | 3.89 | 460 | 6 | 94% | very light | not teaching it |
| KANE, TONYA LYNN reviews ↗ | 3.64 | 3.62 | 195 | 4 | 79% | average | not teaching it |
| DRAKE, JEANA reviews ↗ | 3.97 | 4.00 | 79 | 1 | 100% | - | not teaching it |
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.
Grade records describe outcomes. For what a course is like to take, read student reviews written on dibs below or follow the separate external review link.
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 109L. Read from Fall 2026, because dibs has not read a class page for EE BIOL 109L in Spring 2027 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 Springs
Ran in 3 of the last 3 Springs.
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, three hours; four field trips. Requisites: course 109 (may be taken concurrently), Life Sciences 1 or 7B. Introduction to marine environments and methods used to study them. Exploration of variety of concepts in marine science, ranging from oceanography to behavior, primary productivity, and marine biodiversity, with emphasis on experimental design and scientific writing. 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 Spring 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.

Final enrollment, averaged across each term's sections: between 19 and 20 a term over 7 terms, summer excluded, most recently 20 in Fall 2025. That is the shape across years, not this term, which is above.
Seats over time in Spring 2027
Read once so far, so there is no line to draw yet.
What turns this into a chart
A second reading is what turns this into a chart: courses come round within about three hours, and a lecture somebody is watching goes to the front of the pass. Watching is on the lecture's own page, not this one.
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.
