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

dibs has not read this section's restrictions yet, so alerts on it are held. Check the registrar before counting on a seat.

Full grade history for A&O SCI 2

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

  • 2 exams, said by 9 reviewers
  • 5 quizzes, said by 8 reviewers
  • 5 problem sets, said by 2 reviewers
  • Labs mentioned, no number given, said by 3 reviewers

Read from 80 reviews 12 days 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

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

1 hour plotted. dibs read it.32 of 32 enrolled at the newest reading, 8 days ago, and no seats left. Seats from 5 Sep 03:05 to 5 Sep 03:05, 32 to 32. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. Every hour plotted carries a read, so a count that did not move here was checked and did not move.

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, at the end of the term. Nothing has moved since.

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 posted here.

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

Spring 2026 has ended, so no room can be started here now.
