Complete videocourse of FreeCAD

I would like a multi-class FreeCAD (open source software) tutorial, at first with the most basic concepts (from zero) and increasing the level with each class, starting to beginners and finishing with a professional mastering of the subject, to learn and understand completely how to do 3D modelling and 2D technical drawing. The minimum total duration of the videocourse with all of classes is 8 hours.
