Just thought I'd drop another line to say that I think CLO is the best !  When I first started on Level 4 it was a bit of a shock having many more lessons without "set pieces" and english guidance....you see, I listen to the podcasts going to and from work, and trying to make sense of the explanations given in chinese was a bit dangerous, to say the least ( particularly when I had to keep refering to the english transcripts, Haha ).  But now I'm getting used to it...there is so much repetition that my understanding is becoming more "instinctive", and I'm preparing for each

CLO is progressive so it helps reminding the bases and the written language (thanks to the new feature that teaches how to write the characters). It is also a real online "tutor", and everyone knows that repetition is the only way to learn a foreign language with efficiency. I also use Chinesepod as a complement for spoken language. I think these two chinese podcasts should not be considered as competitors, but as complementary tools. I hadn't spoken chinese for three years until I found your website. I am so happy to recover my former level and even more.
