The registrar's own records: 4,518 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 3.41 to 3.98.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.

- P 4 of 4,562
- NP 1 of 4,562
- I 37 of 4,562
- NR 1 of 4,562
- DR 1 of 4,562
Percentages are of the 4,518 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), no report (NR), 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.
No assignment details are available in this review summary. Based on 102 reviews; source checked about 1 month ago. Missing details do not mean there are no papers or exams. Check the current syllabus.
What comes first
The chain dibs can see is 2 courses long before CHEM 14CL. Read from Fall 2026, because dibs has not read a class page for CHEM 14CL in Fall 2025 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for CHEM 14BE, CHEM 20B, CHEM 20BH, and CHEM 20L, so the real chain can only be longer than this, never shorter.
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, two hours; laboratory, four hours. Enforced requisites: courses 14B or 14BE, and 14BL; or 20B or 20BH, and 20L; and 14C (may be taken concurrently); all with grades of C- or better. Synthesis and analysis of compounds; purification by extraction, chromatography, recrystallization, and sublimation; characterization by mass spectroscopy, UV, NMR, and IR spectroscopy, optical activity, electrochemistry, pH titration. P/NP or letter grading.
Sections in Fall 2025
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 22 readings. That term is over, so nothing has moved since.

From the people who took it
Student reviews
What taking CHEM 14CL 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 2025
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 1 minute
Both readings say 311 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.
