This book is again a wonderful tool to use in adult ESL classes. I love Interchange books for my class because of the rich contents and interesting conversation drills for students to practice with.
The only issue my adult students have had with this Level 1 Interchange textbook is that some of the contents in the book are too difficult for them. I think Level 1 is a big leap from Intro Level - so I usually prepare extra worksheets and activities to help my students grasp the contents better. Overall, this is a great ESL textbook.
