I would like to learn Mandarin very badly and am willing to study hard and work for my goal. There are no teacher in my town (already looked) so I figure Rosetta Stone would be a safe bet. Have you used it before for any language? I heard that I may want another source for grammar. What do you recommend, from your own experience? Are there ANY Rosetta Stone success stories out there? Thank you so much for your time! I greatly appreciate it! -Someone
