The actual best way is to move to the country where it's spoken and get friends (ideally a sexual partner) who speak that language exclusively. You'll gain proficiently very quickly. Of course, it's going to be harder to do that with Arabic. I've never had a lot of luck with Rosetta. It often came away with the wrong meaning of the words, etc. I prefer knowing a little of the basic grammer to see what's going on first. This makes it easier to learn other related languages. I learned a good amount of French in a few days because the verb forms and latin roots are so similar. Rosetta is like asking a native speaker the rules of their grammer. Can you say why you speak the way you do - other than "that is/ is not right"? I can't very well.
