I'm curious, do you know how many total hours the average person would spend going through all 3 levels and doing all the available exercises in each lesson? The reason why I'm asking is I read in the Rocket News that the Foreign Language Institute (FLI) specified a certain number of hours for a person to become proficient in speaking a second language. For example, I'm using Rocket Spanish and the FLI said it would take somewhere between 575 - 700 hours to become proficient. If I went through the entire 3 levels of Rocket Spanish doing all the available exercises, could I expect that I would be fairly proficient in the language? I realize everyone is different and the ability to absorb and retain what you've learned depends on the person. I also understand the FLI study was based on students that were in class 25 hours per week in a small classroom environment (6 students) which probably enhanced their learning by having more individualized attention from the instructor and being immersed in the language.
I gather the best way to learn a language is to immerse yourself in the language and culture by visiting a country that speaks the language you're trying to learn, but I'm just trying to figure out what I can expect seeing the program through from beginning to end.
