I'm just a hobbyist, and I've been playing with Blender for over ten years now. I'd consider myself at least an "intermediate" user, but I cannot overstate how useful this course is, even designed as a beginners' course. Not only is it an invaluable reference tool that I return to time and again, but I'm still finding Blender features that I'd overlooked, or didn't pay enough attention to the first time around. Zach's teaching style is easy to follow, and the example project is huge fun (I decided to alter it to a train to give it my own spin!). Even though Blender is now much older, this course is still extremely applicable.
