Where WordPress lacks in its implementation as a LMS is its inability to create and post grades for students to see. Cue KB Gradebook.

Activating this svelte plugin allows a professor or teacher to quickly and painlessly create and update grades via a .CSV file uploaded into WordPress.  Students have access to their own specific grade page by entering a specially created password based on their e-mail address.

Sadly, overtime this plugin tends to deteriorate.  Joseph Ugoretz explains that it is the plugin’s inability to handle apostrophes.
