Final
Not read yet
dibs has not read this class page since it started reading exam times, so it does not know either way.
Grades
6,721 letter grades, everyone who has taught MATH 31B.
Read 3 hours ago. dibs reads this about once an hour, so the seats and the instructors here may both have moved since.
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
Tell dibs what you have already taken and this line will say which of these you have. Your list.
From the registrar new students only until 15 September
Information on the Mathematics Diagnostic Test and Advanced Placement (AP) credit is available at https://uclamathugrad.zendesk.com/ . Seats are held for entering students who enroll through New Student Orientation sessions beginning July 2, 2026. New student restrictions will be lifted on September 15, 2026 at 8 a.m. Enrollment is contingent on taking and passing the Mathematics Diagnostic Test. There will be two MANDATORY midterm examinations from 6 to 7:50 p.m. on Monday, October 19 and Friday, November 20, 2026.
Held for entering students enrolling through orientation until 15 September. If that is you, the seats are yours now; if not, the class opens to you that morning.
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.
dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.
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.

Unchanged over 14 days
A dot is a reading where something moved: the seat count, the status, or the waitlist. The last one is the last time dibs read this section, moved or not, and that was 3 hours ago. It is where the line stops, not where the count is now. The line holds flat between dots because that is what the readings say: it did not drift, it held and then jumped. The ticks along the bottom are the hours dibs recorded reading this section, which is how a flat run says "checked, unchanged" rather than "nobody looked". It only keeps those from 25 August, so the ruler is shorter than the line for now. Both start when dibs did rather than reaching back before it existed.

Class chat
Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.
Dis 3E shares one room with Lec 3 and every other discussion under it, because that is what a student means by "my class".
Reading a room needs no account. Posting does, and it is free.
