Superb online school
I've started a one-to-one online course 4 months ago and I'm really impressed by my progress. I had 'zero' knowledge of Mandarin and now I can understand and speak a little bit. My teacher is simply amazing. She has not only superb human qualities but also an infinite patience. I fell really lucky for having her. There is still a long long way, but I'm sure at the end of the way I'll succeed. I strongly recommend GoEast if you plan to learn Mandarin in a hassle-free way.
