Hi, Kal! Glad to hear that you're ready and keen to learn Spanish! In my opinion, that attitude--in and of itself--will get you farther than the particular language-learning package you choose.
We've seen really impressive results with people using Rocket Spanish because of its focus on *communicating*, not memorizing verb tenses. But, of course, not everyone gets that far in three months. I'd say that the crucial factor dividing those who achieved the results and those who didn't was attitude. People who had a real drive to learn dove right into the material, practiced every chance they got, and basically made it their goal to learn Spanish NOW. If you live, eat, and breathe a language, of course you're going to learn it faster than someone who's fighting it every step of the way!
That being said, you raise a really good point. Fluency isn't just about being able to communicate your needs and get around in a foreign country (which Rocket Spanish aims to teach). Really, fluency is about being able to hold complex conversations and communicate whatever you want to say without the language holding you back. It probably takes years of immersion in a foreign country to get to that point!
I guess what we wanted to emphasize is that Rocket Spanish will get you *speaking* Spanish, not just being able to get the right answer on a test. With our Interactive Audio Course, you should find it pretty easy to hold basic conversations in Spanish right away! And if you're speaking with your co-workers in Spanish on a daily basis, you'll find that your communication skills will grow by leaps and bounds.
For Mauricio and me, it's not being able to use perfect grammar that matters as much as being able to* communicate* in whatever way possible. When people stress out about using the right word grammatically, they end up censoring themselves and feeling like they can't say anything right in Spanish. Don't _ever _buy a course that makes you feel that way!
That being said, Rocket Spanish has a comprehensive grammar course as well, so if you want it you'll have it.
Because of your excellent point, though, we're going to change the wording on that phrase to make it reflect more of what we really wanted to say. We wanted to emphasize the fact that Rocket Spanish will get you speaking Spanish confidently in a natural way that isn't going to sound "book-taught."
