The Microsoft Excel training course is not only for newbies who do not know anything or know only a little about the Excel application. It is designed for everyone who wants to master this application. Since Excel is useful not only for businesses and office purposes, even people who do not work in the office or do not have business can also apply for the course.
If you think you are not a newbie anymore and Microsoft Excel training is just a waste of your time and money, you could be wrong. You could be a master of the MS Excel 2003, and feel comfortable with it. But the newer version, the Excel 2007, have new features you would want to learn. Training will further increase your capabilities. And, it is always better to learn and explore new things than being a master of old ones, which might soon become obsolete. From time to time, newer versions with newer features are released, so it is important to keep abreast with these developments.
