I purchased Rocket Korean in August of 2016, yet I have just now begun exploring just how many things it can do! I absolutely love it and get online everyday. I have a 2 hour minimum study goal per day, and with Rocket Languages, it is SO easy to accomplish that! The two hours fly right by!
One thing I don't like is how in the Interactive Audio Lessons, there are TONS of extremely long phrases I've already found just in Module 1. I haven't even bothered studying them because it's 1) irrelevant to me and my study goals, and 2) it's simply too hard for a beginner to learn without knowing the bits and pieces that make up the phrases. In other words, I'd like either the long sentences to go away, be able to select which vocabulary I want to study, or the teacher to break it down to every word in the sentence.
All in all, my Rocket Languages experience has been awesome. As a 15 year old, it's hard to find language learning material I can afford and also be extremely useful and worth the money. And now I know by the amount of Korean knowledge I already have is that Rocket Languages definitely meets my strict criteria as a teenage language learner!
