I would certainly go the route of at least getting some courses with feedback. I self studied a language for 2.5 years while living abroad, and while competent, am not really satisfied with my progress. The saying is practice makes perfect, but practice makes permanent. With zero feedback, a lot of my self-practice was simply reinforcing bad habits, and incorrect grammar because I was simply doing what I *thought* was right, because I had no one to tell me otherwise.
