Cambridge both cheats the student and teacher with this book. It's just a 99%+ word for word copy of their 2015 "Essential Grammar in Use" with minimal changes in names such as - Elisa to Sarah, and from light-skinned characters to dark- skinned characters. A purely pathetic and deceptive way to mask the same product in seemingly new packaging. I spent several hours researching these ISBN numbers on Amazon USA and Amazon Japan to compare them against my existing "Essential" book without any conclusive evidence they were the same. They are exactly the same but 2 years apart publishing date, different titles, and slightly larger pictures yet deceptively marketed as different books.
Really disappointed as a business English teacher in Japan to entrust Cambridge University Press publishing present the same book only with an accent of changes that wouldn't be normally noticed by the average person. Cambridge has intentionally tricked both students and EFL teachers with such sly tactics.
Now I see what they meant by the title "BASIC Grammar In Use" vs. my previous British-based "ESSENTIAL Grammar In Use." The "Basic" label is a way to say that this book is not the same as British English ("Essential" book) and the latter is of higher standard, and therefore you are not getting the same product (although its just a revamp of the former book being over 99% the same thing)..... Pathetic! Never again CAMBRIDGE! I'm done.
