dibs has seen this section open 4 times since 18 August. The last time was 15 September. 2 of those were readings where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

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 about 2 months ago: "Astrophysics, Biophysics, or Physics Majors".

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

Restrictions checked about 2 months ago. This section is cancelled, so there are no openings to watch.

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

  • 2 exams, 4 mentions in past reviews
  • Quizzes mentioned, no number given, 1 mention in past reviews
  • Problem sets mentioned, no number given, 1 mention in past reviews

Based on 82 reviews; source checked 6 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

Not a question any more: see the notice at the top of this page.

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 17 Sep 15:52.

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.

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