1) I started this book on my journey to the certification and after the first read I think it is a good primer to the overall topic and curriculum. It is based on an understandable example and covers the testing idea up to whole test management and tool selection 2) On my second read I skipped every optional parts and it is sometimes difficult to see, if examples belong to optional paragraphs due to the missing blue text color. Besides that, nothing remarkable to add. 3) Final read, felt well prepared and managed to succeed in the exam. And I also bought this course on Udemy in a sale for a fraction of the price and it was well-worth the money: https://www.udemy.com/course/istqb-certified-tester-foundation-level-praxistests/
