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.

Percentages are of the 3,527 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), 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.
What the work looks like
- 2 exams, said by 6 reviewers
- 4 quizzes, said by 3 reviewers
- 5 problem sets, said by 4 reviewers
Read from 152 reviews about 1 month 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. 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. 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 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.

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.
Looking for more perspectives?
External reviews are separate and do not count toward the dibs rating.
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 · Scerri, E.R. · 348 of 348 enrolled
Same seat count, but the status went closed to waitlist and the waitlist went 6 of 6 to 4 of 6 over about 2 months
All 43 readings say 348 of 348.
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.
