I've been around the language learning game for about 10 years now. (Programs, methods, etc. I have 1000s of books in 20+ languages) At first, as with any program, I'm skeptical. Rocket Languages is fantastic, to say the least. It gets you speaking, using real world situations and phrases that bring your conversational fluency up very quickly. The mobile app is awesome, I use it at work and at the airport/ while traveling. I wish there was some sort of package deal because I see myself buying them all. I recommend this program to all my friends that want to learn a language.
Really the only complaint I have is that the 3 levels isn't offered in every language, and that I live behind my computer because this stuff is addicting :D
Rocket, if you see this is there a package deal for everything? :D
