Judging by the comments here, it seems it may vary between schools. Mine has a system where you “apply” for graduation. They just go over your records to make sure you’ve earned all the correct credits and enough of them. Once they’ve verified it they let you know they have and that you now have the degree. I’d probably check with your advisor if you have one, or if not contact the school and ask if there are any steps you need to take once your required classes have been completed.
