I knew no Korean, but was going to travel there, so I borrowed this item from the library (fortunately I didn't waste my money to buy it!) to try to learn a bit of Korean. I didn't learn a thing.
The lesson goes way to fast for a beginner. They jump right in with full sentences spoken at near-full speed. There is little effort made to build on previous vocabulary, no grammar, no breaking down sentences into pieces, no review, just one sentence of random (to me) sounds after another.
I can't believe anyone can learn a language with this CD. Maybe, just maybe, if one listens to it 25-50 times, but there has got to be faster ways.
The phrases themselves are OK, not great. They cover the basics, but some are a bit suspect. "I'd like to buy a roll of film" can probably go.
This might be useful to someone with 1-2 semesters of Korean, to learn some good phrases. But everyone else, avoid.
