Wherever possible, we’ve included the answer keys to the textbook and the workbook right in the course where you need it.
However, you can also download the answer keys directly from the publisher’s website:
* Answers to grammar note practices ("练一练") in the Textbook is not available as these questions are open-ended sentence completion exercises that do not have standard answers.
** Workbook answer keys also include the audio transcript of the listening exercises. Answer keys are sometimes at the very end of the file.
