You can check your grades using blackboard.  Here's how.

On a computer connected to the internet, go to the address bb.gcccd.net.  Do not enter www first as part of the address.

Click on "User Login"

For “Username” enter firstname.lastname, lower case, no spaces, but a period between the first and last name.  

For “Password” enter your birthday in the format mmddyy.

This should be the same login you use for the computers in the physics/astronomy computer room.  If that doesn’t work, ask your instructor.
