72 hours? CORRECT

or it doesn't matter which assignment I log in as long as I log in something? CORRECT

That way I can wait for doing that assignment much later because I am waiting on a book I ordered that is crucial for that particular assignment, so I'd rather wait a few days. You can submit assignments in any order, so long as you don't exceed 72 hours between submissions.

(I hope I make myself clear?) Crystal

GREAT question.
