A: We do not have any planned limits to the number of courses we will have in each topic. Each of our courses is about an hour long and covers a wide range of topics. We will continue to release new courses for each topic (like Excel and Access) every month until we're out of topics. Quick frankly, I don't see an end in site. As long as there is material to cover, we'll be creating new courses!

In our classroom-based Microsoft Access course, for example, we have six, 3-hour classes. That's 18 hours of training covering beginner through advanced material. Expect to see at least 18 classes for Microsoft Access released over the next few months. Windows, Word, and Excel will all probably have at least 10 or 12 classes each by the end of the year.

How many do you need to buy in order to be proficient? You can learn the basics with just one of our videos. After taking our Excel 101 course, for example, you'll know how to build a basic spreadsheet. Each class after that will build on your knowledge with a few new topics. After completing the 100-level courses (101, 102, 103, etc.) you should be more than proficient in that software. If I had to guess on a number, I'd say after 3 or 4 of our courses, you'd be pretty knowledgable.
