How to catch up with advanced group? We live in the USA. My 12 yo daughter was transferred to a private middle school for gifted children and joined Mandarin class, where students already studied for 2 years. She is trying to catch up, but apparently it is more difficult than we thought at the beginning of the academic year. While we consider hiring a private tutor to help her to catch up, I wonder if you can suggest any resources, free and paid, which would be useful to help my daughter - websites, books, language learning packages, etc. Is there any good course on Coursera you can recommend? Is Anki convenient for learning Chinese words? Is Rosetta Stone good, in your opinion? Or is http://www.chineasy.com/ would be good for this purpose? Any ideas will be highly appreciated.
