Richard, you are correct. If you've already taken my Basic and Intermediate Excel 2000/2003 courses, then you probably won't learn anything new in Excel 2007 Basic 1. It's for beginners.

If you want to get up to speed on the changes from 2003 to 2007, then pick up the Upgrading to Excel 2007 seminar which covers all of these differences.

I will say, however, that I am planning to cover much NEW material in the upcoming Excel 2007 EXPERT series, so you probably will benefit from those.
