My Spanish Coach actually surprised IGN, both in what they managed to pick up in the relatively short amount of time they had with the lessons (though they'll see how long they can retain them) and how well it delivered them. Picking up on things like gender and age, emphasis and the breakdowns of the actual language itself and proper/casual ways of conversing are made fairly clear and reinforced regularly.
It's by no means a replacement for a full-blown language course, but it's also a fraction of the price and with a thousand lessons covering almost 10,000 words and a good 700 phrases, it'll at least get you to the point where you can be comfortable in being around Spanish-speaking friends... even if you may not yet have the confidence to try actually speaking it yourself.
