Hi, There are a few free ones on the site but the majority of the training is classroom level instruction - put into video format so there is a lot of value in them. The content there at the moment is equivalent to attneding a full 1 week fundamentals, 1 day 2d draft, 2 day surfacing, 2 day ST update and 2 day ST2 update - plus much more.
We do have a YouTube Channel that has some excerpts of the full material.
