the registrar has this letter grade only this term

The registrar's own records: 2,893 grades over 5 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

1 of those terms is a summer session, and summer sessions are counted here.

The table below splits them, and term averages across those 5 terms ran 3.87 to 3.91.

Percentages are of the 2,893 letter grades. Grey bars are non-letter outcomes: 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.

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.

What the work looks like

  • Papers mentioned, no number given, said by 1 reviewer

Read from 2 reviews 26 days ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.

What comes first

The chain dibs can see is 2 courses long before LIFESCI 7L. 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.

From the registrar's catalog

(Formerly numbered 23L.) Lecture, one hour; laboratory, three hours. Requisite: course 7B. Recommended to be taken concurrently with course 7C. Introductory life sciences laboratory designed for undergraduate students. Opportunity to conduct wet-laboratory and cutting-edge bioinformatics laboratory experiments. Students work in groups of three conducting experiments in areas of physiology, metabolism, cell biology, molecular biology, genotyping, and bioinformatics. 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 : the oldest of these 29 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 620 and 848 a term over 4 terms, summer excluded, most recently 691 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Fall 2026

How each lecture has filled since dibs first saw it.

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.

dibs read 168 of the 176 hours its hourly record covers, 95%, and did not look in 8. dibs had no hourly record before 24 Sep, which is the other 886 of 1062 plotted.588 of 588 enrolled at the newest reading, 13 minutes ago, and no seats left in its discussions. Seats from 18 Aug 20:40 to 2 Oct 01:25, 615 to 588. dibs read 168 of the 176 hours its hourly record here covers, 95%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 8 hours dibs was keeping a record and did not reach this section. Nothing before 24 September at 18:00, where this section's record starts, has a read either way, which is 886 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.
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.
