Final Drafts?

[ss20ts]

First you submit it as a Rough Draft. The professor will return it to you with feedback. Sometimes they will want changes. Sometimes they will say submit it as it is. Either way you have to submit it again as the Final Draft. You'll see those 2 buttons when you go to submit the Final Assessment - Rough Draft and Final. Always submit a Rough Draft unless you've missed the deadline at the end of the session.

Do they follow the same 72 hour rule for returning drafts as with milestones?

The professors are supposed to follow the rule. Some don't which is super annoying. I started emailing the professor to let them know I submitted my Rough Draft. Some professors have said that they don't get the email alerting them to the Rough Draft being submitted. Probably lost in the spam folder or wherever email gets stuck in the internet.
