Well, you ought to start because a calendar is very helpful in organizing your schoolwork, as well as your life. You should access your Syllabus or Course Schedule, and enter all of your class tasks into your calendar. Don't forget to enter your non-school obligations, too, so you can organize your days and weeks. The most important thing, perhaps, about using a calendar -- whether it's of the traditional variety, on the web, in Blackboard, or in a mobile electronic device -- is to check it several times a day.
