Mike, thanks for posting that question, because as I was refreshing myself with Rule 6, I came upon the answer to one of the questions I had trouble with on the exam. You might remeber me posting this.
A kick which is blocked in an offside direction may be legally recovered by any player.
This is covered in 6.3.5(2).
Now I know why I couldn't find it, who'd expect a ruling about a kick to be listed in the Passing Rule.
Good thing the exam isn't due for a few more weeks
