Alwaysbehind about covered it; 4-H doesn't usually get much more involved than that in English classes in my neck of the woods.
You might look into your local 4-H central office and pick up a horse rulebook. In my state, the rulebooks have excellent descriptions of what classes are available and what is expected/required in each class. I'd expect that there's something similar published for other states.
