The course content is very good. However, while the initial lessons included explanations of calculations and Excel functions, I found it somewhat disappointing that as the course progressed, it increasingly used content from practice Excel files and proceeded without explanations of the Excel functions. Although the course content itself becomes more complex toward the end, if the early parts provided detailed explanations about why certain methods should be used, then the latter parts should have also explained why specific functions need to be used for beginners, or why the Excel formats provided in Monte Carlo are set up that way. While it was easy to follow initially, perhaps due to my limited knowledge of statistics, I can understand and follow the flow, but the question of "why this particular method was used" remains unresolved.
