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.
Its a big waste that i bought this book. it has just five pages and for that they have cost 238 rupees. No where they have mentioned that there will be only five pages. If i had know this before I would have never bought it. By the time my daughter gets attracted to the book and turns the pages there are no more pages to turn.
