How can I learn if the book is SO wrong?

Upon enrolling at University of Pretoria and attending my first Financial Accounting 121 lecture, we told to purchase "An introduction to the understanding of accounting for different entities," ISBN978-1-928481-51-5.

The book is absolutely riddled with errors and typos, making it extremely difficult to know whites going on if you missed a lecture where an error was corrected.

I am also not speaking about small insignificant errors, although those are abundant too, these are incorrect accounts and amounts used in examples and activities!

It's a total mess.
