I've found several errors in her books. Since I am not full time faculty nor the coordinator for the A+ courses, I don't get to pick the textbook.
And I don't have contact with the author.
While no book is completely error-free, I have always
made myself available to my readers via email (and this forum). I have received many comments and questions over the last 20+ years my books and videos have been published, and have used this valuable feedback to continually improve and de-bug them.
I do my best to sell th expert's book !
I surely do appreciate that, thanks! Scott.
