That's a neet little program. Over the years I have played around with many different learning techniques to increase my code speed. If your a touch typist, a good touch typist the computer based ones work pretty well. But if you have to hunt for the right key to type to respond they teach you a bad delay habit because you can't do that and copy code. I have used tapes, but they are not adjustable to your learning curve and you are stuck with one frequency that may or not work well for your ear. The MFJ pocket tutor worked the best for me but everyone learns codes differently. If you decide to take your code test, the testing device will probably send around 900 to 1000 Hz so it's best to learn at that audio frequency.
