This course is not designed to be used with a soft keyboard on a tablet, although it has been successfully tested to work with iOS devices (iPad and iPhone). If you are on Android or a Windows Mobile device it is hit or miss, however it should work absolutely fine with an external keyboard. It is highly recommended to learn touch typing on a physical keyboard for the tactile feedback, and bluetooth keyboards can be obtained very inexpensively these days (. as little as $10). This is a VERY worthwhile investment to learn touch typing, a skill which will last you a lifetime.
