This is an amazing series! I have just gone through the Tones 2 video and practice drill. I have not found clear explanations and exercises like these anywhere else! I an pleased that my premium subscription is going towards such exciting development of the ChinesePod program.
Now when I go through a lesson I can use this guidance to help me pronounce everything much more clearly than I did before.
Sorry, next comment is rather off this topic.
I would greatly appreciate itl if you were to do another series like this on learning characters. I have tried making up nemonics and learning all the components. I haven't succeeded very well. I actually find that I am learning better by reading sentences in hanzi while I am listening helps me better in learning to recognise characters, but learning to write then without looking at an example is very far behind. Your help would be greatly appreciated. I expect others have the same problem.
