The registrar's own records: 1,577 grades over 9 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

No summer session is in that record.

The table below splits them, and term averages across those 9 terms ran 2.74 to 3.51.

Historical grades for KERANEN, JUKKA PETRI MIKAEL, across recorded terms. The course summary above includes all professors.

  • D- 12 · 1.7%
  • F 23 · 3.3%
  • P 1 of 713
  • I 5 of 713

Percentages are of the 707 letter grades. Grey bars are non-letter outcomes: passes (P) and 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.

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.

Read the source reviews

What comes first

The chain dibs can see is 1 course long before MATH 31AL. 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.

From the registrar's catalog

Lecture, three hours; discussion, one hour; laboratory, one hour. Preparation: at least three and one-half years of high school mathematics (including some coordinate geometry and trigonometry). Requisite: successful completion of Mathematics Diagnostic Test or course 1 with grade of C- or better. Not open for credit to students with credit for course 31A. Intended for students who still need to review precalculus material (laboratory) while starting calculus. Differential calculus and applications; introduction to integration. P/NP or 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 7 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 99 and 212 a term over 9 terms, summer excluded, most recently 202 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 700 hours its hourly record covers, 24%, and did not look in 532. dibs had no hourly record before 2 Sep, which is the other 392 of 1092 plotted.200 of 210 enrolled at the newest reading, 3 hours ago, with 10 left in its discussions. Seats from 17 Aug 15:07 to 2 Oct 02:32, 126 to 200. dibs read 168 of the 700 hours its hourly record here covers, 24%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 532 hours dibs was keeping a record and did not reach this section. Nothing before 2 September at 23:00, where this section's record starts, has a read either way, which is 392 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.
