You are looking at Winter 2027. Enrollment for it has not opened, so these are the registrar's early listings. dibs holds 3,430 sections for Winter 2027, read 3 days ago. Separately, it has finished 2,460 of the 3,592 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: 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.

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

  • A+ 270 · 9.3%
  • A 2,170 · 75.0%
  • A- 220 · 7.6%
  • B+ 108 · 3.7%
  • B 67 · 2.3%
  • B- 22 · 0.8%
  • C+ 7 · 0.2%
  • C 15 · 0.5%
  • D 5 · 0.2%
  • F 9 · 0.3%
  • I 2 of 2,895

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.

What comes first

The chain dibs can see is 2 courses long before LIFESCI 7L. Read from Fall 2026, because dibs has not read a class page for LIFESCI 7L in Winter 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.

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 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 28 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 Winter 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.
