The registrar's own records: 7,758 grades over 16 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
3 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 2.70 to 3.62.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.
- A+ 680 · 8.8%

- D+ 2 · 0.0%
- D 151 · 1.9%
- D- 6 · 0.1%
- F 76 · 1.0%
- P 28 of 7,818
- NP 7 of 7,818
- I 23 of 7,818
- DR 2 of 7,818
Percentages are of the 7,758 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.
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
Reported assignments across instructors and terms. This term's syllabus may differ.
What the work looks like
- 2 exams, 6 mentions in past reviews
- 4 quizzes, 3 mentions in past reviews
- 5 problem sets, 4 mentions in past reviews
Based on 152 reviews; source checked about 2 months ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.
What comes first
The chain dibs can see is 1 course long before CHEM 14B. Read from Fall 2026, because dibs has not read a class page for CHEM 14B in Spring 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.
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, one hour. Enforced requisite: one course from 14A, 14AE, 20A, or 20AH with grade of C- or better. Enforced requisite or corequisite: Life Sciences 30B or Mathematics 3B or 31B with grade of C- or better. Not open to students with credit for course 14BE, 20B, or 20BH. Chemical equilibria in gases and liquids, acid-base equilibrium; phase changes; thermochemistry; first, second, and third laws of thermodynamics; free energy changes; electrochemistry and its role as energy source; chemical kinetics, including catalysis, and reaction mechanisms. P/NP or letter grading.
Sections in Spring 2027
Choose an open discussion to enroll; an open lecture alone does not mean a seat is available.
Seat counts as of : the oldest of these 14 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 208 and 356 a term over 13 terms, summer excluded, most recently 345 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
Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.
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.
From the people who took it
Student reviews
What taking CHEM 14B was like: the work, the teaching, and what students wish they’d known.
Your experience could be the first.
No student reviews are available to read on dibs for this course yet. Took it? Tell the next person what helped, what was hard, and how you spent your time.

External reviews are separate and do not count toward the dibs rating.
