As an ASVAB tutor who published study guides, I saw the need to create video courses to correspond with my study guides.  To help improve ASVAB math scores, I designed video courses to go with the math books I wrote and the ASVAB prep course I teach.  The Mathematics Knowledge video course I created consists of videos for about 200 Mathematics Knowledge problems that are found in the matching study guide.  The videos provide step by step explanations of the algebra and geometry problems on this section.  The video course is available for $49.  It is more affordable than the live tutoring classes and provides more help than the study guides provide.
