Progressive, proven, and it works
I like the bite sized videos and the supplementals (links, apps, etc). The foundation and sequence of learning tracks were very useful to my progress. I had a few natives compliment my pronunciations! Some of the emails received were not relevant based on my interactions - not an easy workflow to overcome, but that is not an uncommon experience with others. I feel the value of the courses are great considering how affordable they are. I would recommend anyone wanting to learn Mandarin to give it a try.
