Longman Keystone C Paperback – January 1, 2010

Very very good book, is used like new inside, thank you , is for my son.

It was an used book but it looks like new. My daughter love (and I) that it was in that good condition. Also the books areive in a eeally short time.

First of all I love learning. On the other hand reading English is indispensable habit for me. Keystone books are good designed books for English learners.

Good conditions....

This is an excellent series of books that was recently published in June of 2013. There are a total of 8 books in the series including"Keys to Learning", "Building Bridges", "A", "B", "C","D","E", and "F". It is excellent for an ESL program geared toward content based instruction. Each book has content from a variety of academic disciplines including science, history, literature, mathametics, and other topics of interest. We have been using "Bridge Builder" and want to move on to "Book A". Understand that the publication date is just recently in 2013 and NOT the 2007 date I keep seeing for every item in this series.
