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.

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.

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 limited on both passes

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. Discussion sections 1A, 1C, and 1E are limited to junior/senior departmental majors and minors on the priority, first, and second enrollment passes. Any student meeting the requisites may enroll beginning July 1, 2026 at 8 a.m., space permitting. Discussion sections 1B, 1D, and 1F are limited to juniors and seniors on the priority and first enrollment passes. Any student meeting the requisites may enroll on the second pass, space permitting. The department does not use PTE numbers. Do not contact the instructors or advising office for a PTE number.

The limit applies on both enrollment passes, so there is no later pass to wait for.

Restrictions read 4 days ago. dibs re-reads these slowly because they rarely change; watch the section and it moves to every 6 hours.

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.

dibs read 168 of the 529 hours its hourly record covers, 32%, and did not look in 361. dibs had no hourly record before 10 Sep, which is the other 534 of 1063 plotted.116 of 120 enrolled at the newest reading, 7 minutes ago, with 4 left in its discussions. Seats from 18 Aug 19:40 to 2 Oct 01:25, 100 to 116. dibs read 168 of the 529 hours its hourly record here covers, 32%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 361 hours dibs was keeping a record and did not reach this section. Nothing before 10 September at 01:00, where this section's record starts, has a read either way, which is 534 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.

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: 7 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.
