How much more detailed are the Live / On-demand Webinars compared to the online modules?

The online recordings are generally more detailed and thorough than the live classes. 

The live classes focus on the “core” parts of the curriculum whereas the online recordings cover the whole curriculum.  The live classes will miss out certain readings to allow the instructor to spend sufficient time on these core areas.  The main benefit of these live classes is the pace and structure: having only two sessions a week allows a delegate to keep up with the pace of learning.
