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

dibs has not read this section's restrictions yet, so alerts on it are held. Check the registrar before counting on a seat.

Discussions

You enroll in the discussion, not the lecture, so the seat figure above is the sum across all of them and can read open while every discussion you could actually join is full.

4 discussions, none open. There is no waitlist either, so the only way in is somebody dropping the lecture.

No discussion is open. Whatever the lecture reads, there is currently nothing here to enroll in.

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 11 reviewers “At the beginning of the quarter, she told us that we'd be focusing on quantum mechanics and that it'd be an important topic, just to not have any questions on the final covering that topic.”
  • Quizzes mentioned, no number given, said by 3 reviewers “There were 3 quizzes, one question each.”
  • Papers mentioned, no number given, said by 1 reviewer “a final paper, which sounds like a lot (12-15 pages)”
  • Problem sets mentioned, no number given, said by 5 reviewers “do the problem sets each week”
  • Presentations mentioned, no number given, said by 1 reviewer “There're also two presentations that were really chill and a final paper”

Read from 336 reviews 3 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 29 Aug 03:05.
