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.
A good book, covers most of the elements of a public speaking. Only drawback will be the language, it is quite high-standard, hard to understand sometime. A lot of theory and downloads, so people needs to concentrate a lot to understand. Overall a good book. I faced issue with Amazon service, they did not deliver as mentioned timelines, the product was delivered 4-5 days late and they would keep changing the arrival date of products. Not accepted.
Nice book.. we like amazon because of providing nice varieties of books.. But i when i saw the books, down of it has mentioned as free delivery. But, after adding to the cart, carts subtotal has increased to 50 ruppes, because of delivery charge.. whats this? just mention whether its free delivery or not in the down of the book..
