This course book comes under English for Specific Purposes (ESP) materials which is designed for teachers and students as well. The former can use it as a reference teaching textbook in the classroom for they can choose topics that may be relevant to the major of their students; the latter may use it on their own as a self-study material in order to improve and enrich their vocabulary in management, finance, accounting and the other related majors. Additionally, the subjects used in this course book are entirely seen by the students in other courses, which are usually delivered to them in Arabic or French. This will help them learn the same concepts in different languages so as to better understand them. For this reason, most of the lessons are accompanied by a trilingual lexicon that contains a list of the key terms seen earlier in the lesson. On the other hand, and unlike textbooks of this kind, we thought it would be more relevant if we start the book by an English placement test to help the teachers group their students in accordance with their level of English.
