I’ve inserted several notes into your work. Be sure you are reviewing these notes. There are some definitions and procedures you need to work on.

At the very end of your Assignments page there is a link entitled ‘open qa’, designed to help students with some of the basic concepts that I find give students difficulty. You should consider working those problems, as indicated, and submitting the results. There are about eleven sequenced questions in those topics.
