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.
This book is all about financial savings.. I bought it in Hindi so that those who're finding it hard to earn get some sort of Motivation but it's all about investing and savings... Nothing about earning! Such a hype!
