I'm a 22 y/o engineering student and I've be trying to learn german for a little over a month now. I took spanish in school up until high school, but never really liked it and didn't really have the drive to learn it so i decided to switch to german. I decided to go with rosetta stone as it seems to be the easiest and I heard it works well. I'm about halfway through level 2 and I'm liking it so far, but has anyone successfully learned a language this way? Did you feel fluent after you were done with all the levels, or could you just follow the jist of what people were saying? How long should I be using rosetta stone per day? an hour or more? What else is good to supplement rosetta stone?
