Korean Level 1
(St. Louis, MO, USA)
I found Rosetta Stone immensely helpful and my Korean students were impressed by my rapid progress. I think one of the key things is to commit at least a half hour to an hour per day for maximum progress. I thought it was pretty fun, but I'm a bit of a language junkie. I had some technical difficulties getting the headphones to register my voice, but eventually worked it out. Totally effective, I would buy it again (and when you are finished with it you can resell it for most of its original value if you've taken good care of the product).
