Radically Simple Accounting has been used as a textbook for awhile. Recently, it's been picked up at the university level. And not just any University, but Northeastern University in Boston, MA. Believe it or not, that is the university I attended for my freshman & sophomore year. I was an older student, turned 21 in the dorm, so I was more motivated than my classmates, studied hard, and became valedictorian my sophomore year. And now they're the first university to use my book as a textbook. It's a small world!
