You are looking at Fall 2025.
That term is over, so these are last term's numbers rather than seats you can take.
dibs holds 1,964 sections for Fall 2025, read 18 days ago. Separately, it has finished 527 of the 3,494 courses on its own sweep list for this term. Terms nobody is enrolling in are swept one a night in rotation, so a course with nothing here may simply not have been reached yet.
