Free samples

Each of the three books has its own sample PDF (12 pages, including 1 page explaining the sample): the cover, contents, foreword, how to use the book, one unit opener, all four pages of one lesson, and the answer key for that lesson. No email address needed.

About the samples

Each sample is a separate file extracted from the full PDF. Its first page lists the pages included and the source version; every page is stamped with its original page number.
