Know the Due Dates
Know when assignments are due. In online assignments in some classes, when they are late the assignment will "disappear" from Blackboard right after the due date and/or they might not be accepted.
Getting Information
If you need help understanding the assignment, contact the instructor. If you need help working with problems, proofreading, etc., go to tutoring.
Turn it In
Turn it in 24 hours before it is due if possible. This prevents it from being late if something happens like your internet doesn't work.
