This was excellent. I consider myself to be pretty adept at excel. I've had challenges understanding, indirect, index/match and sumproduct. The program spelled them out in a way that made it logical and very applicable for future use. I also liked the tips on summing among different tabs. This was a very practical course.

Good course overall, I definitely learned things. I feel like the same amount of time was given to some of the simpler things as was to the harder ones, though. For example, indirect/address seemed to go really fast. You could almost have a course on each of those later ones. Good job though.

This course was very thorough in teaching someone how to not only understand the underlying principles of commonly used and more complex formulas, but also a lesson in how to construct a workbook so that less manual manipulation and user error occurs.

Instructor did a great job walking through the material. When the advanced formulas were covered, these a little difficult to for me to follow. I expect to go back and review those sections, but this was not the fault of the instructor.

I consider myself an excel power user and I found some new things in this. The only thing that bothered me was the use of CountA vs count which I think would reduce the risk of errors when he was showing the offset formula.

I liked the course. I enjoyed the offset part that I think could be useful in making YTD formulas more automated.. Thanks

Two exam questions were super confusing. Not well written. #2 and #4, other than that, was an excellent course
