This is an excellent program from several aspects. First, it is probably the most cost effective option out as to providing bang for the buck. Secondly it approaches the learning experience from several angles. You have audio and visual reinforcement. The audio lessons are very comprehensive and can be listened to while you are driving. The manual is very well written (lot of work was put into this) and goes hand in hand with the audio material. The vocabulary app helps reinforce the material in a fun way. This a very comprehensive program and well worth the money.
