Registrar's Restrictions cell, read 6 days ago: "Computer Engineering, Com Sci, Com Sci and Engineering, Electrical Engineering, Ling of Com Sci, Undeclared Engineering Majors, or Cog Sci, C&S Bio, Math of Computation Majors or Premajors or Bioinfo, or Data Engineering Minors, and 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

Students who enroll in upper-division courses offered by the Samueli School without completing the requisites are subject to disenrollment after the second class meeting. If necessary, consult with an OASA counselor through MyUCLA Message Center.

Restrictions checked 6 days ago and may be outdated. Unwatched sections are rechecked less often than watched sections. Check the registrar before counting on a seat.

Checked 168 of the 1147 hours with hourly history, 15%. No reading was recorded in 979 hours. dibs had no hourly record before 29 Aug, which is the other 267 of 1414 plotted.40 of 60 enrolled at the newest reading, 8 hours ago, with 20 left. Seats from 18 Aug 18:40 to 16 Oct 15:34, 39 to 40. 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 8 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.

Class chat

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

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