I have been using Blender around for 6 years but the new 2.8 version is a big challenge for everyone, with learning the program almost from the beginning. This is why I ordered the course as I already know the “Mastering Sculpting in Blender” by Zach which is a masterpiece itself.
I'm very satisfied since the whole structure of the content is so well thought through and clearly explained. I like it very much, that you don't need to download the files and can watch it online. Also, I like the short length of the videos, so it is easier to remember if you would like to watch a part again. The short description under the videos as text reference is very useful as well, so there is no much need to take individual notes.
Some words about Zach yet - he is so consequent and building up the training like the German national football team their actions (they won the World Cup in soccer four times), and already trusting so much in him that being afraid not to buy anything he sells in the future. But seriously, he is a perfect professional and indirectly teaching more than Blender here.
