Put this class on a board
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.
What watching takes
Your setup, with any current hold shown beside the watch control.
An account
An alert needs an email address. You can browse courses and grade history without signing in.
Your year
Helps dibs interpret enrollment limits. Uncertain eligibility may still be included with a caveat.
When you can enroll
Set your appointment or acknowledge that an open seat may not be available to you yet.
A watch slot
25 per account. A lecture watch also covers its discussions. Paused watches still use a slot.
Before you can enroll
Tell dibs what you have already taken and this line will say which of these you have. Your list.
From the registrar Registrar note
Enrollment is limited to Physiological Science majors on the priority, first, and second enrollment passes. Any student may enroll beginning September 15, 2026, space permitting.
The new-student hold ended on 15 September.
Restrictions checked 7 days ago and may be outdated. Unwatched sections are rechecked less often than watched sections. 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.

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.
What the work looks like
- Quizzes mentioned, no number given, 2 mentions in past reviews
- 1 paper, 2 mentions in past reviews
- 1 presentation, 1 mention in past reviews
Based on 8 reviews; source checked about 1 month ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.
Will it still be here
high risk chance of closing before your enrollment pass.
Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

Seats over time
Unchanged over about 2 months
Both readings say 70 of 70.
A dot is a reading. Recorded enrollment counts match, so the line is flat across the whole window: it says when dibs looked rather than what changed. The last dot is the last time dibs read this section, moved or not: 37 minutes ago.

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.
Class chat
Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.
Reading a room needs no account. Posting does, and it is free.
