This is a set of the latest Business Manager Certification Exam study materials, 5th edition, including the essential points master and problem set. The textbook has been read once. There are no folds or markings. The red sheet for the problem set is also included. Both books are in excellent condition as they have been stored with book covers. ★Same-day shipping available! I passed the exam using these two books. Perhaps the study method using the red sheet while commuting on the train was effective? I was able to remember the key points. What do you think?
