I am looking to take the Lync Server Certifications for Lync 2013. However, I'm having a hell of a time finding any training that is any good. We typically use CBT Nuggets for our training. They are great and they explain the material very well. However, CBT only has lync 2010 training. Has anyone found any 2013 training? I've found some stuff but it is not very good. It seems like 2013 training material is EXTREMELY limited.
