Chocofur has a fantastic Beginner Blender 2.8 series on their channel, where they cover the absolute basics in the first videos and move into more advanced tools and methods as the videos go on. He keeps his explanations very slow paced and easy to understand for the viewer, making it very beginner friendly as he explains the ins and outs of the revamped user interface.
You’ll start off with object selection, learning how to rotate and scale, learning the viewport and lots of other core concepts. I always recommend this playlist as Chocofur does a great job ramping up the difficulty and making sure that by the time you’re done the videos, you’re ready to take on more challenging projects
Chocofur updates this playlist at least weekly, so be on the lookout for more videos being constantly added to this fantastic playlist
