Thanks for your question. The IC Workbook DVD has all the dialogues from the Level 1-1 Workbook, but there is also additional listening material that you will find on the Audio CDs. These audio CDs have the textbook dialogues, pinyin practice, and listening comprehension exercises from the textbook and workbook, not all of which are on the DVD.
Hi Charles,
Thanks for your question. The IC Workbook DVD has all the dialogues from the Level 1-1 Workbook, but there is also additional listening material that you will find on the Audio CDs. These audio CDs have the textbook dialogues, pinyin practice, and listening comprehension exercises from the textbook and workbook, not all of which are on the DVD.
I hope that helps answer your question.
