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 about 2 months ago. Separately, it has finished 527 of the 3,617 courses on its current checking list for this term. Future-term coverage is incomplete, so a course with nothing here may simply not have been reached yet.

Is one term a guide to the next?
Across the measured corpus, the same course and instructor's term averages were strongly correlated, including terms several years apart. That is why the adjustment does not weight recent terms more heavily. This is a dataset-wide pattern, not a promise about this instructor's next class.
Teaching it in Fall 2025
This term has ended. Section counts below are historical readings, not current availability.
Reading these figures
Raw is the mean of the recorded letter grades. The adjusted historical GPA pulls an instructor's average toward the course's adjusted average, which itself uses a department prior. It is a comparison aid, not a calibrated prediction or a student rating. Small samples carry more uncertainty. All recorded instructor roles are included, and a section is counted only once for this instructor. Grades cannot establish workload or explain why outcomes differed.
