■ Why Do Model Answers for Case IV Differ Among Schools?
Case IV of the SME Management Consultant Secondary Exam is the only case that primarily consists of calculation problems dealing with finance and accounting. Generally, calculation problems are understood to have a single definitive answer. However, in reality, different exam preparation institutions publish different model answers, causing confusion among examinees. Behind this lies a structural issue unique to Case IV, where multiple approaches can be valid in interpreting the assumptions of the questions and selecting calculation processes.

This article uses Question 3 from the Reiwa 7 (2025) exam as its subject matter, cross-comparing model answers from various exam preparation institutions and systematically explaining where and why the answers diverge. The focal point is the issue of 'timing of investment in working capital.' The article carefully examines why multiple answers can be valid and their rationale, while also delving into the evolution of the exam design itself.
By tracing how previously ambiguous settings have been refined and how the current exam style has evolved, the essential structure that gives rise to 'differences in interpretation' becomes clear. Ultimately, the article presents practical guidelines for making confident decisions on the actual exam.

■ For Examinees Who Want to Know 'Where the Difference Is Made'
This article directly addresses the questions 'Why are the answers different?' and 'Which one should I choose?' — questions that every SME Management Consultant Secondary Exam student encounters at least once. Rather than dismissing the differences in model answers as mere 'ambiguity,' understanding them at the level of exam structure enables you to develop a decision-making framework applicable even to unfamiliar problems. This is a must-read for anyone looking to fundamentally improve their scoring ability on the Secondary Exam.
