Excellent methodology

I am a Brazilian living in Shanghai and trying to learn mandarin for some time without progress. Then, I found Silk Mandarin and now I am at the right path. The blended course has an excellent methodology: you study by yourself before classes and review after them. The online classes presentend by Jasmine are very educative and my teacher, Hanna, is very well prepared. I think the best way to learn chinese is through repetition and Silk Mandarin's program is designed to offer lots of repetion and exercises until you can really learn.
