I have 2 BOM classes, plus I purchased a PP class with Carol Doak. All the classes explained in detail how to proceed with each step and I've learned something new every time. I think what I like best is the fact that I can go back and revisit the class whenever I like and it's always there for me when I'm ready for it, even if it's midnight or 5 AM. Whether you take a free class or purchase one, I think you will be pleased with the classes.
