Before you can enroll

Registrar's Restrictions cell, read 19 hours ago: "Undergraduate Students Only".

Tell dibs what you have already taken and this line will say which of these you have. Your list.

From the registrar Registrar note

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. Wait lists are not possible because of the three-part structure (lecture, discussion, and laboratory). Students who retake Physics 5B must enroll in all three sections: lecture, discussion, and laboratory. Once enrolled, send an e-mail to mtran@physics.ucla.edu with your name, student ID number, and quarter in which you originally took the laboratory. You will be manually enrolled in the G99 laboratory. Any student attempting to hold a spot for another student is violating Student Conduct Code 102.23d and may be referred to the Office of the Dean of Students. See https://pa.ucla.edu/physics-and-astronomy-enrollment-information.html for more information.

The new-student hold ended on 15 September. This class is also Undergraduate Students Only, which the end of the new-student hold does not lift.

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: 21 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.
