As a student at the Business College of Copenhagen, studying English/IT, this has be become one of my most important tools.
Being both easy to use and containing practically every word in English i could possible think of, this is a book that i would recommend anyone who deals with English on a professional level. But at the same time I would also recommend it to those who think that their english skills are perfect, because thos book will expand even the largest vocabulary!
