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

Registrar's Restrictions cell, read 2 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. Students must enroll through Electrical and Computer Engineering M116C.

Restrictions read 2 days ago. dibs re-reads these slowly because they rarely change; watch the section and it moves to every 6 hours.

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

  • Exams mentioned, no number given, said by 12 reviewers
  • Quizzes mentioned, no number given, said by 9 reviewers
  • Projects mentioned, no number given, said by 4 reviewers

Read from 60 reviews 16 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

no history chance of closing before your enrollment pass.

Final enrollment per term from four years of grade data. Summer excluded: different population, different pass structure.

The department has not published seat counts for this class, so there is nothing to plot. dibs records when it read the class, not a count it was never given. Last read 1 Oct 17:23.

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 has posted yet.

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