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 3 courses long before C&S BIO 100. This is a floor, not a deadline: dibs has not read a class page for LIFESCI 30B, LIFESCI 40, MATH 3B, and MATH 3C, 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, two hours. Requisites: Computer Science 31 or Program in Computing 10A; Life Sciences 30A and 30B, or Mathematics 3A, 3B, and 3C, or 31A, 31B, and 32A; Life Sciences 40 or Psychology 100A or Statistics 10 or 13. Modern statistics and data science study that builds competency in computational data modeling and analysis. Designed for Computational and Systems Biology majors. Interdisciplinary topics integrate data-driven statistical and computational modeling, and resampling methods for understanding and modeling data. Key topics include advanced data visualization, simple linear regression, clustering, classification, and dimensionality reduction techniques, the same principles and techniques that are the building blocks of machine learning. Study is modular, with opportunities for peer collaboration and proposal writing components. Acquired knowledge and skills may immediately be applied in research or industry settings. 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 4 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

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.

dibs read 168 of the 761 hours its hourly record covers, 22%, and did not look in 593. dibs had no hourly record before 31 Aug, which is the other 294 of 1055 plotted.53 of 60 enrolled at the newest reading, 3 hours ago, with 7 left in its discussions. Seats from 18 Aug 21:40 to 1 Oct 19:42, 41 to 53. dibs read 168 of the 761 hours its hourly record here covers, 22%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 593 hours dibs was keeping a record and did not reach this section. Nothing before 31 August at 03:00, where this section's record starts, has a read either way, which is 294 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.
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.
