Fixed a small typo and removed the audio files. @DougNoGit I think we should go the Activity route and later we can implement the slides as fragments since if we're converting an existing Android application to use fragments, and we sort of are since the education module has not change too significantly, we would move code from our existing activitys' callback methods (onCreate onCreateView et cetera) into the respective callback methods for the fragment. So since we are pressed for time with the upcoming deadline for the intial release of version 2 let's do that and then once we have that working we can transition those activities to fragments.
