1999-02-05 good for example questions-many inaccurate answers

The book was good for example questions, there were 600 questions in the 4 tests, but when I scored the test and went back to see which questions I missed, I found that there were many inaccurate answers in the key. Such as...a question in the first test asks how many ventilations are adequate for artificial respiration? the key gave the answer of 5 and went on the say that 3 is adequate for a child. not quite- 12 for an adult and 20 for a child. There were too many to name. This really isn't good for a test that helps you do WELL on the exam- maybe a qualified instructor should review the test and its answers!
