The registrar's own records: 1,364 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 3.19 to 4.00.

Percentages are of the 1,364 letter grades. Grey bars are non-letter outcomes: 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.

|---|---|---|---|---|---|---|---|
| RIGUEUR, DIANA reviews ↗ | 3.96 | 3.97 | 600 | 8 | 99% | very light | not teaching it |
| LOWRY, WILLIAM EDWARD reviews ↗ | 3.29 | 3.28 | 337 | 4 | 50% | light | not teaching it |
| NAKANO, ATSUSHI reviews ↗ | 3.32 | 3.31 | 329 | 4 | 47% | average | not teaching it |

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.

What comes first
The chain dibs can see is 4 courses long before MCD BIO 144. Read from Fall 2026, because dibs has not read a class page for MCD BIO 144 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 20B and LIFESCI 23L, 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, three hours; discussion, one hour. Requisites: Life Sciences 3, 4, and 23L, or 7A, 7B, 7C, 23L, and 107. Not open for credit to students with credit for Chemistry 153B. Development of thorough understanding of fundamentals of modern molecular biology both from perspective of known molecular mechanisms for regulating fundamental processes in cells and from theoretical applied perspective for using molecular biology as laboratory tool. Special emphasis on molecular mechanisms that relate to chromatin and histone modifications, DNA replication and repair, transposition, microRNAs, meiosis, and splicing. Application of molecular biology as tool to understand embryonic development, reprogramming, cancer, and stem cells. Development of sophisticated understanding of DNA, RNA, and protein as well as capability of designing experiments to address fundamental questions in biology and interpreting experimental data.
