oh man, scheduling software can be a real headache. tbh, most of these systems sync in a few ways. sometimes it's like a live update, so any change a teacher or admin makes gets pushed out instantly to student schedules. but other times, especially with older systems or if it's trying to save resources, it syncs on a timer. like, maybe it pulls new info every 15 mins or once an hour from a main database. that's usually why you see delays or why it feels out of sync sometimes. the instant push is better but harder to manage with lots of users.
