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 analyses reviews to verify trustworthiness.
I would say it's not one of the best book to read on public speaking.The language used brings down its rating for me. The headlines and chapters heading are correct and what is required to excel in public speaking,but the explanation for that where it suffers. You can avoid buying it if you are just starting in public speaking.
A fantastic book and not too expensive.But very very very poor page quality which is a major problem.And when we buy the book,only the half of book is downloaded and then it asks to pay again for the full book.
