Hello!
I’ve just started a couple of weeks ago and I haven’t been taking the courses in order at all. Sometimes I’ll even be taking two at one time. I would say it kind of depends on the level your at skill wise. For example, I had never used blender before. I had used other software like Maya though. I started with blender basics, then moved on to some of the animation stuff, and took some of the modeling courses at the same time. I think it really just depends on what you want to do and what skill level your at! But that’s just me! Hope that helped!
