First of all, I would like to thank Duolingo for creating this phenomenal app! I didn't do so hot in French during High School and my teacher made it boring. If only it would have been on my iPad and iPhone, and the class time was spent discussing culture and difficult areas of the language, I think everyone would be passing with flying colors.
Thanks again! After I complete French, I will be writing an entire post on here as a thank you, in French of course.
