I bought LA Spanish 1-5 several weeks ago and have finished 1 & 2. I know that is faster than you recommend but the way way you have things sturcted I have found my retention has been very high even with trying to do a lot quickly. I did take 3 years of spanish in high school but that was a long time ago and had forgotten most of it. I wanted to provide a tip for your users on something I think really helped me. After the first couple of lessons, i decided the order I was going to listen to the dialogue was going to be No subtitles, spanish subtitles and then both. This way it forces to me to listen to the conversation first without seeing any words and I can see how much I comprehend. I think this strengthens and accelerates the comprehension and solidifies what you already know. This is the most dificult part of learning a new language, understaning the spoken word and generating a reply. Thanks for putting out a great product.
