CLUSTER 70A · Dis 1D
Evolution of Cosmos and Life
This is a year, not a class
Clusters run across three quarters, fall, winter, then the spring seminar, and UCLA counts the credit on completing the yearlong cluster: four GE requirements and the Writing II requirement. Signing up for the first quarter is signing up for the year.
Dibs only reads Fall 2026, so the later parts show no sections here: that is this term, not the sequence ending. What you keep if you take only part of a cluster is a question for the Cluster Program, not something these numbers answer.
Seats, time, final and grades
Seats
Closed.
25 of 25 enrolled.
Its lecture reads closed (275 of 275 · 1 over enrolled): you attend both, so this seat is not one you can take while that holds. There is no waitlist either, so the only way in is somebody dropping the lecture.
Meets
W 9:00am-10:50am
This discussion only. You also attend Lec 1.
Final
Wed 9 Dec, 8:00am to 11:00am
One exam for the whole class, Los Angeles time.

Grades
1,293 letter grades, everyone who has taught CLUSTER 70A.
Read 31 minutes ago. This is a recent reading, not a live seat count.
dibs has seen this section open 40 times since 17 August. The last time was 22 September. 20 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.
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 5 hours ago: "First-Year Freshmen Only".
From the registrar limited early, then open
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. Upon satisfactorily completing Clusters 70A, 70B, and 70CW, students receive credit for the following requirements: two Life Sciences GEs (one with lab), two Physical Sciences GEs (one with lab). Upon satisfactorily completing Clusters 70A, 70B, and 70CW, students will fulfill the Writing II requirement. Students must receive a grade of D- or better each quarter to receive general education credit and continue in the course. To receive credit for Writing II, students must satisfy Writing I by the end of the year, successfully complete fall and winter quarters, and earn a grade of C or better in spring quarter. For a complete summary of clusters credits, see https://www.uei.ucla.edu/academic-programs/ucla-cluster-program/benefits . There will be two MANDATORY midterm examinations from 6 to 7:50 p.m. on the following Thursdays: October 15 and November 19, 2026.3
The limit stands until 15 September, and lifts then. dibs still counts this class as one you can take, but not yet. This class is also First-Year Freshmen Only, which that date does not lift.

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 read this course’s reviews and none of them say what kind of work it sets, so dibs has nothing to show rather than a guess. Read from 96 reviews about 1 month ago. That is the reviewers being silent, and not a course that sets no work.
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.

40 times reopenedA 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: 31 minutes ago.

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
One dibs reader watches this class or has it on a plan. Nobody has posted yet.
Dis 1D shares one room with Lec 1 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.
