The registrar's own records: 6,691 grades over 17 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
4 of those terms are summer sessions, and summer sessions are counted here.
The table below splits them, and term averages across those 17 terms ran 3.11 to 3.78.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

- F 49 · 0.7%
- P 12 of 6,785
- NP 1 of 6,785
- I 81 of 6,785
Percentages are of the 6,691 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.

Based on 92 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 14BL. Read from Fall 2026, because dibs has not read a class page for CHEM 14BL in Summer Session A 2026 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.
From the registrar's catalog
Lecture, one hour; laboratory, three hours. Enforced requisite: course 14A or 20A or 20AH with grade of C- or better. Enforced corequisite: course 14B. Not open to students with credit for course 20L. Introduction to volumetric, spectrophotometric, and potentiometric analysis. Use and preparation of buffers and pH meters. Synthesis and kinetics techniques using compounds of interest to students in life sciences. P/NP or letter grading.
Sections in Summer Session A 2026
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 9 readings. That term is over, so nothing has moved since.

From the people who took it
Student reviews
What taking CHEM 14BL 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 Summer Session A 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.

Unchanged over 2 minutes
Both readings say 129 seats.
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.
