I have the books from ASA. I have a competing Windows product that requires Internet to function. This product allowed me to work on memorizing items needed for the written no matter where I was or if I had any connections. And it allowed me to run a practice test, but I needed the test supplement (which I have). Im now signed off to schedule and take the real one, because of being able to study when I could (very busy person who is on-call). I couldnt do that w/ the competitors product.
