Hey @mauroornelas
Don’t let the Blender version fool you into thinking it would not apply anymore.
The knowledge taught in the older courses on the site is still relevant, just because Blender changes, the core concepts of 3d do not.
We always recommend using the Blender version that is used in the course whilst in the beginner stages of learning. Once you have more experience with Blender, the version you use is less of an issue.
Happy Blending!
