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 happened to see about the book in a site where for the very first time science notes are given based on real life applications. As a teacher when I search for the real life applications and Competency based questions and spend more time in Internet for myself and for students, this book is one complete package. Bought both grade 9 and 10 science and its fabulous work by the writers and big Thank you to Educart for this book which is literally a life saver for me and y students.
