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.

What watching takes

Your setup, with any current hold shown beside the watch control.

An account

An alert needs an email address. You can browse courses and grade history without signing in.

Your year

Helps dibs interpret enrollment limits. Uncertain eligibility may still be included with a caveat.

Before you can enroll

Registrar's Restrictions cell, read 42 hours ago: "Undergraduate Chemical Engineering Majors".

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Restrictions checked 42 hours ago and may be outdated. Unwatched sections are rechecked less often than watched sections. Check the registrar before counting on a seat.

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

  • Papers mentioned, no number given, 2 mentions in past reviews
  • Presentations mentioned, no number given, 2 mentions in past reviews
  • Labs mentioned, no number given, 1 mention in past reviews

Based on 10 reviews; source checked 7 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

high risk chance of closing before your enrollment pass.

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

Seats over time

Nothing read since 16 Oct, 18 hours ago. Over about 2 months before that, filled by 1.

Checked 162 of the 1253 hours with hourly history, 13%. No reading was recorded in 1091 hours. dibs had no hourly record before 25 Aug, which is the other 173 of 1426 plotted.18 of 20 enrolled at the newest reading, 18 hours ago, with 2 left. Seats from 18 Aug 04:30 to 16 Oct 13:13, 17 to 18. 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 18 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 1A shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
