Enroll on the registrar

A board is one quarter you are drafting, so it needs an account to live in. Signing in brings you straight back to this page, with this class still in front of you.

Before you can enroll

Restrictions checked 9 days ago and may be outdated. Check the registrar before counting on a seat.

Discussions

You enroll in the discussion, not the lecture, so the seat figure above is the sum across all of them and can read open while every discussion you could actually join is full.

9 discussions, none open. No waitlist listed.

No discussion is open. Whatever the lecture reads, there is currently nothing here to enroll in.

What students say

dibs measures outcomes: grades, seats, how fast it fills. For what the class is actually like to sit in, BruinWalk has the reviews.

Workload, very light. 5.0 of 5 for Qinbin Li, where 5 is lightest. Read 28 days ago.

What the work looks like

2 exams, 9 mentions in past reviews
5 quizzes, 8 mentions in past reviews
5 problem sets, 2 mentions in past reviews
Labs mentioned, no number given, 3 mentions in past reviews

Based on 80 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.

A&O SCI 2 reviews for Qinbin Li, one of 4 listed Reviews for all professors of A&O SCI 2

Will it still be here

Not a question any more: see the notice at the top of this page.

Checked 168 of the 169 hours with hourly history, 99%. No reading was recorded in 1 hour. dibs had no hourly record before 13 Oct, which is the other 1375 of 1544 plotted.

A dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not. Fall 2026 enrollment is over, so that is a last reading, not a live count.

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.

Discussions

When it meets

Grades i An estimate based on historical registrar grades, not a student rating. Instructor estimates are pulled toward the course and department average in proportion to how little data there is, so a twelve-person seminar cannot top the list on noise. The sample size is printed beside it.

What students say

Will it still be here i The worse of two readings: how full this section is right now, and how quickly the course has historically filled. A tier rather than a percentage, because reserved seats make any number optimistic: an open seat may be held for a major or an intake you are not in.
