There really shouldn't be any errors in this stupid book, considering that this is a deciding factor of whether an RN program will accept you/your scores or not. ATI makes a ton of money off this scam, they should have it proof read multiple times before publication. I hate that there are so many errors in this book. If I fail the TEAS (which in my humble opinion is a waste of my money, I may not get into the program due to typo errors.) Its all about making money off everyone, and finding ways to make even more by adding all these stupid entrance exams that have no bearing on whether you will exceed in your nursing skills and abilities or not. Again, my personal, humble opinion.
