Am I in the right room?

I was wondering if this course is the immediate next course after finishing the "Learn the Blender Basics" course. Because I'm 2:47 in and boy am I confused.  

The "Mesh Modeling Fundamentals" course was named so I'm going over there, but is it optional? Is that why this course is listed directly after "Learn the Blender Basics" instead of "Mesh Modeling Fundamentals"?

My question may be as confused as me but hmu if you know the answer. Thanks!
