The registrar's own records: 862 grades over 13 terms, 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, and term averages across those 13 terms ran 3.06 to 3.53.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.
- A 218 · 25.3%
- A- 192 · 22.3%
- B+ 146 · 16.9%
- B 104 · 12.1%
- B- 113 · 13.1%
- C+ 24 · 2.8%
- C 38 · 4.4%
- C- 16 · 1.9%
- D 4 · 0.5%
- D- 3 · 0.3%
- F 4 · 0.5%
- I 3 of 866
- DR 1 of 866
Percentages are of the 862 letter grades. Grey bars are non-letter outcomes: 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
Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.
dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.
What comes first
The chain dibs can see is 6 courses long before CHEM 154. Read from Fall 2026, because dibs has not read a class page for CHEM 154 in Summer Session A 2026 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for CHEM 20B 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.
From the registrar's catalog
Lecture, two hours; laboratory, eight hours. Enforced requisites: courses 153A or 153AH, 153B or 153BH, and 153L, with grades of C- or better. Recommended: course 156. Two to three major laboratory projects using biochemical laboratory techniques to investigate contemporary problems in biochemistry. Topics include transcription activation, molecular basis of DNA-protein interactions, biochemical basis of platelet activation, and initiation of blood clotting cascade. Experiments entail characterizing function of proteins, nucleic acids, and lipids involved in these processes. P/NP or letter grading.
