3,594 letter grades, everyone who has taught LIFESCI 15.

Read 26 minutes ago. This is a recent reading, not a live seat count.

dibs has seen this section open 14 times since 17 August. The last time was 1 October. 7 of those were readings where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

Enroll on the registrar Sign in to watch for an opening

Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

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

From the registrar limited early, then open

Conflicts between examinations and activities in other courses cannot be accommodated, so avoid conflicts when enrolling. Due to the curriculum of this course, enrollment will be closed by 3:00 p.m. on Friday, October 9, 2026. Late enrollment is rarely granted and requires instructor approval. PTE numbers are NOT available; do not contact the instructor or the Life Sciences Core Office for a PTE number. The department will not facilitate section switches between students; students should enroll in a section only if they can attend all quarter. Seats are held for entering students who enroll through New Student Orientation sessions beginning July 2, 2026. New student restrictions will be lifted on September 15, 2026 at 8 a.m. There will be one MANDATORY midterm examination from 6 to 7:50 p.m. on Thursday, October 29, 2026.

The limit stands until 15 September, and lifts then. dibs still counts this class as one you can take, but not yet.

dibs read 168 of the 552 hours its hourly record covers, 30%, and did not look in 384. dibs had no hourly record before 8 Sep, which is the other 530 of 1082 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: 26 minutes ago.

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.

Class chat

Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.

Dis 1P shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".

Reading a room needs no account. Posting does, and it is free.
