As someone who took 3 tests to actually get the passing grade for Morse Code, let me tell you... Practice... conscience practice, constant practice... that is the only way I was able to do it... I tried listening to a mp3 player while working, nothing stuck... only when I used G4FON on my computer for nearly an hour each night was I able to do it. Good luck to you... G4FON like someone else said, is able to make MP3's.
