I have been taking a class on Udemy Academy, by Luis Romero called, Business Fundamentals 2020 Accounting Excel & Stock Research. If you wait for a sale which happens almost every week, it only costs 13.00. I have learned a great deal, and it is a program, so there are 3 more classes to come. Already, we have learned about financial statement analysis, business analysis, and the business cycle, and I am only 60% through the first class. This is a link to the class to the site. The instructor is Luis Romero.
