    My experience with DuoLingo as well. I've learned Portuguese, Spanish, and some Italian with it, but Mandarin seems to fall short. I'm liking HelloChinese so far. Source: over 5 years ago
  • Seeking advice on improving mandarin and chinese skills
    I don't think Rosetta Stone will be nearly advanced enough for you, from what I recall it's quite basic. I'm personally really liking HelloChinese as a way to learn and practice, but again I'm far below your level. I've heard good things... Source: over 5 years ago
