TLGs a key part of the new Fast Learner Modules
Hey TLG fans and fast learners,
I recently published the first series of Fast Learner Modules in the TechNet Wiki. These new articles are designed to be a self-contained learning experience for a specific technical topic. Fast Learner Modules include a video (with transcript) and review questions (with answers).
An additional key element is a link to a resource to practice or work with the technical info presented. In the absence of a TechNet Virtual Lab, I cannot recommend a better resource for hands-on practice than a Test Lab Guide (although I may be a bit biased :>).
Check out the series of Fast Learner Modules for SharePoint 2013 claims authentication:
Note the use of SharePoint TLGs for the 
Practice section.
Enjoy your learning!
