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.
One of the most practical books on pencil sketching. It is a reproduction of an old book and not properly formatted for Kindle. I found that it is perfectly readable on an iPad but not on a mobile phone nor on a Kindle e-reader.
I downloaded this book on my Kindle reader and the page size was so small that no matter how much I enlarged the font, the book was unreadable. I can't comment on the content because, I CAN'T READ IT!!!
