why can i find some courses on the calendar but not on acorn?
i’m not really sure. i’ve seen this happen in calendar entries for programs, ie. a program will list a course but when you click on the hyperlink, you get an error. that usually just means a course used to exist but isn’t being offered anymore. but if you’re seeing full course entries in the calendar (you click on the hyperlink and the course description, prereqs etc show up in a different page) that aren’t showing up on ACORN, i have no idea why that might be.
you could try testing the course codes in the timetable as well? if something doesn’t show up on both ACORN and the timetable, i think it’s safe to say that course isn’t being offered for the upcoming year.
if a course you’d like to take shows up on both the timetable and calendar but won’t pop up on ACORN, i’d recommend that you get in touch with the offering division and see what’s up. maybe it’s an internal error. i dunno.
i hope this helped, and good luck with course enrolment!
