You are looking at Spring 2027. Enrollment for it has not opened, so these are the registrar's early listings. dibs holds 3,658 sections for Spring 2027, read 47 hours ago. Separately, it has finished 2,718 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: 6,784 grades over 16 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 16 terms ran 3.42 to 3.82.

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

  • A+ 1,323 · 19.5%
  • A 3,311 · 48.8%
  • A- 582 · 8.6%
  • B+ 391 · 5.8%
  • B 401 · 5.9%
  • B- 230 · 3.4%
  • C+ 144 · 2.1%
  • C 226 · 3.3%
  • C- 86 · 1.3%
  • D+ 7 · 0.1%
  • D 32 · 0.5%
  • D- 3 · 0.0%
  • F 48 · 0.7%
  • P 3 of 6,804
  • NP 2 of 6,804
  • I 13 of 6,804
  • DR 2 of 6,804

Percentages are of the 6,784 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), 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.

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.

What comes first

The chain dibs can see is 3 courses long before LIFESCI 107. Read from Fall 2026, because dibs has not read a class page for LIFESCI 107 in Spring 2027 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for CHEM 20B and LIFESCI 23L, so the real chain can only be longer than this, never shorter.

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

In Springs

Ran in 4 of the last 4 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

Lecture, three hours; discussion, 75 minutes. Requisites: courses 7C, 23L, Chemistry 14A (or 20A), 14C (or 30A). Not open for credit to students with credit for course 4. Advanced Mendelian genetics, recombination, biochemical genetics, mutation, DNA, genetic code, gene regulation, genes in populations. 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.

Seat counts as of : the oldest of these 30 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 284 and 429 a term over 12 terms, summer excluded, most recently 370 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.
