In some of the posts, I refer to things in the Integrated Chinese textbooks. For some previous classes I’ve used Integrated Chinese, Level 1, Part 1, Third Edition and Integrated Chinese, Level 1, Part 2, Third Edition. Currently, the class I’m in is using Integrated Chinese, Level 2, Part 1, Third Edition.
IC1-1 covers chapters 1 – 10, plus some introductory stuff on tones, radicals, etc., while IC1-2 covers chapters 11 – 20. Both parts are available with Simplified or Traditional characters, though the classes I’ve taken use the Simplified version.
IC2-1 starts the chapter count anew, but contains both Simplified and Traditional characters.
