Before you read what I have to say, see what my students are saying about my courses on Excel:

“I would like to tell you that I am very impressed with your courses so far – I particularly like the short videos that allow me to get to a topic quickly and then move on (your competitors mostly offer 20-30 min videos which is a bit much to keep one’s attention span). The other gem in your training are the shortcuts, I found no other course with the same insights.” by Peter Klugsberger, Australia, ex-McKinsey & Co., served various senior roles (CEO, COO) in various companies

“I thought you knew me – You solved the exact problem which I face at my office in your course” by Rajesh Dhoot, India, ex-Sr. Manager, Finance and Accounts, Ultratech Cements – An Aditya Birla Group Co.
