If you miss a few days, as I did for my brother's out-of-state wedding, the program allows you to go back to any point to re-do the lessons to freshen your memory, Rosetta Stone or to make sure that what you learned stuck. Sometimes, I'll listen to a lesson over and over until I can decipher the exact nuances of the sounds. The program also comes with a microphone, and it forces you to actually speak - and it won't let you go forward until you say the words more or less correctly.
