I have been using Excel for over 20 years, but there is a difference between being good at something and being able to teach it. In that time I have taught hundreds of people how to master its power. Because I have taught so many people, I know not to assume you already understand something, and I have probably already heard every question you are likely to have.
This course took over 4 months to produce, and has been tested extensively with scores of people. If something didn't work, or wasn't clear, it was revised until it did. Of course, we never stop learning, and I will continue to develop this course and your skills with your feedback. And remember, if you have a question, post it in the forum and I will answer it for you personally.
Get this course now, and...enjoy!
