Query: Not Adequate

This book might have covered the exam material in sufficient detail back when the pass marks were set in the low 60% range, but now they are set at 75%+ this book is not adequate. This is particularly true for the second exam. At first glance the book appears to cover all the topics, but it will not give you the level of understanding required to ensure a pass in the exams. Study the book, try some STS exam questions, and you will see what I mean.Consider buying additional material to supplement this for study purposes.
