Selective Continuing Education Classes

Some interior design firms generously paid for their employees to attend CE classes, but usually those classes are selective, I remember my former employer told me to attend some classes, that classes came with 3 parts, but I was only notified on the 2nd and 3rd part of classes but not the 1st one, so I was wondering why, when I went to the 3rd part of class, the class provider mistakenly handed out the handouts for the 1st part of class, and I quickly read through the handouts and found the 1st class was about teaching interior designers how to run their own interior design firms, then I finally understood why my employer didn't want me to go to the 1st part of class.
