Hey @Cate, and anyone else feeling the frustrations,
There are two playlists for those beginning their Blender 3D journey.
your-first-week-with-blender-and-cg-cookie
And
the-fundamentals-to-become-a-skilled-blender-artist
these give the perfect introduction into Blender, once complete and successfully absorbed these skills, the next chosen course will be much easier to follow, and hopefully less flip flopping between courses.
Happy Blending!
