If you try to rush through the course you face two very common language learning dangers: (1) burning out, where you can't maintain the pace, and so give up; (2) forgetting everything you have learned, because you have not allowed time for it to sink in.
Think of language learning as a marathon rather than a sprint.
Five levels means 150 lessons. I spend about one and a half hours per lesson. Not because I am watching slowly, but because I pause to take notes and reflect on things we are being taught. Then I spend about thirty minutes reviewing notes from earlier lessons. This two hours per day is a lot of time, and if I could only spare an hour a day, I would split one lesson over two days, rather than rush through a lesson. That means, one hour a day would require a year to complete all five levels. If you have less than an hour a day, then figure on more than a year.
In terms of the level you will reach: you will not be fluent at all. You will have a basic conversational level. Fluenz courses get you over the first hurdle to fluency, but you are still far from being able to speak the language easily. To achieve higher levels of fluency, you will need lots of exposure to native speakers, including talking a lot with native speakers, listening to radio and TV, and reading novels and newspapers, etc.
