I have completed Pimsleur's Spanish 2 and found it to be very helpful in teaching me conversation useage! I have now begun Spanish 3 and find it to be equally valuable! I find it best do listen to the lesson every day until I have mastered about 80% just as the instructions suggest. It takes me about a week. The chief advantage for me in using the Pimsleur method is that I gain confidence in my ability to converse in Spanish and not worry when I make mistakes.This is definitely worth the investment of money and time!
