Is it worth the time??

Has anyone seen this videos/material (http://www.senfinance.com/cfa/index.html) . . . and is it worth the time. Is it relevent to the material/Does it add any value ???

its just the basic stuff … I dont think it will of major help … but if you have no background in finance … then it can be starting point but not a way to get you through the CFAI curriculum
