I subscribed to Babbel Complete for $125 USD. I am studying four different languages now, and I get unlimited time online to study every day. The exercises are well-designed, and you can choose your own course material depending on your needs. For example, if you need vocabulary more than you need grammar, you can study the vocabulary first and worry about verb tenses later. I studied languages in college, and I can honestly say that I never acquired the same level of fluency in a college course even though I paid a lot more money for the instruction. The online review manager lets you go over the material that fits your individual needs, so each student gets personal instruction and can move at his or her own pace. I am very happy with this service.
