Many courses in the department of Physics and Astronomy use the eLearning System (this is known by some people as WebCT or Blackboard Vista). It can be used either to post grades only, or can used for you to take things like math quizzes, turn in your homework or other content. Each instructor within each course may have different requirements. Check with your them to see what, if anything, they are using this semester, and what are the specific requirements for you section of the course. Instructor emails can be found at http://physics.tamu.edu/ . Note that some courses use Mastering Physics which is a completely separate system.
