Grades
1,856 letter grades, everyone who has taught ASTR 5.
Read 8 minutes ago. dibs reads this about once an hour, so it is as current as dibs gets.
dibs has seen this section open 13 times since 17 August. The last time was about 5 hours ago. 6 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.

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 120 reviews 3 days 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.

13 times reopenedA dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots means it did not drift, it held and then jumped, and 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: 8 minutes ago.
Across the 409 hours from 17 Aug 16:42 to 3 Sep 16:30, dibs holds a read record for 168 of them. Where the line is flat across an hour dibs did read, the count held: that is checked and unchanged, rather than nobody having looked. For 11 hours dibs was keeping a record and did not reach this section. Nothing before 27 August at 06:00, where this section's record starts, has a read either way, which is 230 hours of this window. A hedged line never means the readings are doubtful. It means the stretch between them is unaccounted for.
