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 book of propaganda with no other value. The author is no less than the founder of Turkish Studies department at Exeter University. The department is commonly known to brainwash young Turkish with a potential in future Turkish politics. The book attempts to brainwash the reader as well. The author shows no shame to charge $50. I am ashamed to fall for it and pay.
