How to get a CRE level eductaion from online materials

[Michael Ference]

Hello everyone, 

I recently attended a CRE course in my area and the education was absolutely fantastic. It went into specific details as opposed to the general salesly sort of stuff. I was wondering if you all could recommend books or online learning materials that have that same level of information, I'm really looking for detailed analysis on how to do things as an agent at a higher level of undertanding.

Thanks!
