The registrar's own records: 3,299 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 2.92 to 3.90.

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

F 27 · 0.8%
P 1 of 3,308
I 4 of 3,308
DR 4 of 3,308

Percentages are of the 3,299 letter grades. Grey bars are non-letter outcomes: passes (P), 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.

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 EE BIOL 100. 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.

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 01 Oct 13:12: the oldest of these 13 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

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.

Lec 1 · Gorlitsky, L. and Lipman, A.J. · 204 of 240 enrolled

dibs read 168 of the 526 hours its hourly record covers, 32%, and did not look in 358. dibs had no hourly record before 9 Sep, which is the other 556 of 1082 plotted.

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.
