Before you can enroll

Registrar's Restrictions cell, read 3 days ago: "Sophomores and Above".

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

From the registrar enrollment limit

The Psychology Department does not use PTE numbers. Instructors and the advising office do not provide PTE numbers for Psychology courses. Enrollment is limited to junior/senior departmental majors, Neuroscience majors, and Cognitive Science pre-majors on the priority and first enrollment passes. Junior/senior departmental pre-majors and Neuroscience minors may enroll on the second pass. Any sophomore/junior/senior may enroll beginning September 15, 2026, space permitting. You must attend the discussion section in which you are enrolled.

This limit ends at an enrollment pass rather than on a date, and dibs does not hold the date second pass opens for Fall 2026, so it cannot say whether that pass has come. When it does, the registrar writes who may enroll then as “Junior/senior departmental pre-majors and Neuroscience minors may enroll on the second pass.” So dibs cannot tell whether this class is open to you today, and it is not counting it as one you can take: your enrollment appointment on MyUCLA is what settles it. This class is also Sophomores and Above, which the pass does not lift.

Restrictions checked 3 days ago and may be outdated. Unwatched sections are rechecked less often than watched sections. Check the registrar before counting on a seat.

No reading was recorded in 435 hours. dibs had no hourly record before 21 Sep, which is the other 813 of 1416 plotted.204 of 216 enrolled at the newest reading, 3 hours ago, with 12 left in its discussions. Seats from 18 Aug 18:40 to 16 Oct 17:52, 216 to 204. Checks are not continuous monitoring. Changes between checks may be missed.

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, and that was 3 hours ago. It is where the line stops, not where the count is now.

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.
