Specific (Math) Video Lessons for Praxis ParaPro (1755) Assessment?

Does Kahn have LESSON VIDEOS to learn math components SPECIFICALLY on Algebra and Geometry for the Praxis ParaPro (1755) Assessment?  I see the lessons Kahn has for Praxis (mostly all written articles), but I don't really see instructional videos to teach these two math areas specifically for this exam . . . for someone who never had these two subjects in his entire lifetime (me!).  Obviously, I need to learn these two subjects of math at the skill level that will be taught on this Praxis assessment . . . but the challenge is WHERE to find them.  ???
