Hi Dustyn,
It is recommended to use the Blender Version used in the Course you are taking (until you are more experienced and won’t ‘care’ about the Version anymore).
Blender develops really fast and it is impossible to update all Courses 3 to 4 times a year, even without making new Courses. (Production of a Course from start to finish takes about 3 to 6 months and in the case of larger Courses (like HUMAN, for instance) can take years.)
The principles taught in the Courses haven’t changed.
If you insist on using the latest Version of Blender, you will just have to ask, if you can’t find something. But, as Martin @cgtin already mentioned, you’ll have to be more specific as to what you can’t find.
