I am currently learning the Full Stack Power BI course at Excelgoodies, and the overall experience has been very good. The course structure is clear and practical, with strong focus on real-time scenarios rather than just theory.

My trainer, Sami sir, is excellent. He is very knowledgeable and also quite strict, but that strictness really helps in building discipline and understanding the concepts properly. He does not rush through topics and makes sure we understand the logic behind Power BI, DAX, and data handling. Because of this approach, learning becomes solid and confidence-building. The sessions are interactive, hands-on, and assignments push us to think practically. This training is definitely helping me improve my analytical skills and apply Power BI in real work situations. Overall, Excelgoodies is a good choice for anyone serious about learning Power BI and Full Stack BI in a structured and disciplined way.

Elavarasan S, ASIAN PAINTS LTD - SUPPLY CHAIN MANAGER

I first learned Advanced Excel and VBA from Mr. Sami at Excel Goodies in 2014, and that learning became a strong foundation for my career growth ( 4 levels from officer to Manager) . His training didn’t just teach tools—it changed the way I think, analyze problems, and approach real-world data. Mr. Sami is an extremely skilled trainer with deep subject knowledge and a rare ability to explain complex concepts in a simple, structured, and practical way. His clarity helped me apply Excel techniques effectively at various stages of my career.

Motivated by this strong foundation, I recently returned (Aug'25) to upgrade myself through the Full Stack BI program, where I could immediately feel my thinking evolving again. What makes his training truly transformational is the real-world focus. Concepts like power Query, DAX, and various analytics are taught with an “expect the unexpected” mindset. Learning is not theoretical—what you learn in the morning can be applied the next day at work, especially in Microsoft-based environments.

To be frank, This practical approach continues to add real value to my career—in ways even my MBA and MSc could not achieve in day-to-day professional work.
