Course Review Synthesis

Pros:

• Comprehensive Introduction to Power Pivot and Power Query: The course provided a solid foundation in Power Pivot and Power Query, which were new to many users. The introduction to these tools was highly appreciated, as they significantly enhanced the ability to handle data operations.

• Real-World Application Focus: The course emphasized practical applications that can be applied directly to real-world scenarios, showcasing the value of learning through relevant examples.

• Expert Instructor: The instructor's depth of knowledge and experience in the subject matter was evident, providing students with a trustworthy resource for understanding complex topics like DAX calculations.

• DAX Calculations and Practical Examples: Students were able to learn various ways to use DAX functions such as CALCULATE to perform complex calculations and analyze data. The course provided hands-on experience that allowed students to see how these formulas could be applied in their own work, offering a flexible approach to problem-solving and adaptation to different situations.

• Repetition for Key Operations: The course included repetition of key operations such as creating major functions and creating pivot tables, which reinforced learning and helped students remember important procedural steps.

Cons:

• Overlap with Previous Content: Some students felt that a significant portion of the course content (more than half) overlapped with an introductory Power Pivot section, making them question the necessity of retaking this material if they had already studied it.

• Limited Advanced DAX Practice: The course had fewer practical exercises for advanced DAX functions like DATESADD, which could have been expanded to offer a more comprehensive understanding and application of these tools.

• Specific Scenario Validation: The detailed explanation of verifying the accuracy of financial results using SAMEPERIODLASTYEAR was highly valued, but it also highlighted the need for more scenarios where advanced DAX functions could be tested and validated.

General Feedback:

• Usefulness of DATESADD Function: One student pointed out that learning the DATESADD function was effective as it could potentially make some other date-related functions, like SAMEPERIODLASTYEAR, redundant. This underscores the importance of fundamental understanding in these functions for future adaptability and mastery over more complex applications.

• Practical Exercises: Students appreciated the hands-on approach to learning through exercises that allowed them to apply what they learned directly into practice, ensuring that the knowledge gained from the course could be effectively used in their professional environments.

In summary, the course received high marks for its practical approach and expert instruction, with some students feeling that there was room for more advanced content and fewer overlaps with introductory material. The focus on real-world application, particularly around DAX calculations, was particularly valued by the learners.
