if you're a total noob then yes imo. I learned basic words *bought it few days ago*. You will probably have to replay things till you perfectly memorize the words. My personal method: spam the multiplke choice game of your lesson. Once you can associate each word with the romaji, cover the bottom screen and try to remember the actual word and how to pronounce. works for me hehe.

As you already know it is NOT a substitute for taking classes. this is more of a review/introduction software. The refrence book in it is pretty usefull if you carry your DS around. has alot of basic phrases
