How do I grant an individual student an extension on an assignment? Will my gradebook indicate whether or not a student completed an assignment after the due date? How do I add an individual assignment to my course? What are due dates and available dates? Can I use a free version of Canvas with Knewton alta? Can I have alta load in a new tab instead? Why am I seeing dashes instead of scores for alta assignments/ tests/ quizzes in my Canvas gradebook?
