Auditor++ Course/Certification - preliminary table of contents

Below is my preliminary table of contents for Drudget's Auditor++ course and certification.

I don't think it's complete, and I'm interested in hearing what others think. 

Drop me a line at's contact form if you're interested in knowing more about the Auditor++ course or have some recommended topics you want to know more about.
