If you’re interested in learning 3D, specifically Blender, I came across this set of Tutorials that’s formatted in a "class" kind of way:
http://www.gryllus.net/Blender/3D.html
It has videos broken down into different functions and tasks, so it makes it easier to find a specific thing that you’re trying to figure out how to do. Seems like a good place to start learning Blender, and even has some "intermediate" stuff too.
