This tip may be more trouble than it’s worth, but here you go. In the newer versions of iTunes, you can add lyrics to an audio file. If you put the audio file onto your iPod Touch (or iPhone) and play it, you can have the lyrics scroll down the screen while the song is playing. Instead of lyrics, you can put in whatever text you’d like. If, for some reason, you can manage to take a look at your iPod Touch or iPhone while taking your exam, you can play a song and look at the text your added to the file.
