Self-Scored Rubric? HELP!

HELP! Can you guys help me clear up my confusion about the self-scored rubric..

Do we use the rubric given on Blackboard to Self-Score?
    ..Do we just highlight the point value for how we believe we did on the assignment..?

..I'm just not exactly sure what to do for that, and since it is due tomorrow.. 11/2..
I want to make sure I do this correctly.

Thanks for any help I can get! Have a good day!
