dibs
You are looking at Spring 2026. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 21 sections for Spring 2026, read 27 days ago. Separately, it has finished 15 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.

The registrar's own records: 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.

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

  • P 8 of 296
  • NP 3 of 296
  • S 283 of 296
  • U 1 of 296
  • I 1 of 296

Counts are out of 296 recorded outcomes. These are non-letter grades and do not have a GPA.

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.

In Springs

Has not run in Spring in the 3 Springs dibs holds records for, back to Fall 2022. That is 3 years of grade records rather than the course catalog, so it says what has happened and not what the department will do next.

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

Seminar, one hour. Discussion of ethics in graduate education, teaching, and chemical research, including issues such as conflicts of interest, plagiarism, intellectual property, sexual harassment, and other topics related to ethical conduct of research. S/U grading.

Sections in Spring 2026

dibs has not read Spring 2026 for this course, so it cannot say whether it runs. dibs reads the term you are enrolling in first and the rest a little at a time; the registrar's own listing is the answer until this one catches up.
