1. How do I post an announcement to appear in all of my classes without having to type the same announcement in each class?
2. It is near the end of the term and I need to adjust my grade book as I am over by 10 points. Can I reduce the point value on a quiz once its been graded? Will Canvas make the necessary point adjustment for each student? And going forward, when creating a quiz can I "force" the quiz to be worth a certain number of points and will Canvas allocate the appropriate point value to each question accordingly?
