To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
This book contains mostly questions based on the ITIL V3 NOT ITIL4. I did the first few tests and then put it aside because it did not help me prepare for the ITIL 4 foundation exam. I had to constantly search the web to check the answer and the reasoning behind it. Indeed I would like to get my money back.
After doing the class for Foundation 4 and used this book to cram the last week with the Mock Tests... I was not feeling confident on the morning of the tests but I passed with a good score. a lot of that had to do with this book.
