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 analyzes reviews to verify trustworthiness.
My 7 year old and I are massive Harry Potter fans and son was desperate for a potions book. I must say I was pretty disappointed by this book. Frankly, it's something I could have whipped up in a week whilst doing my A levels. It's okay, minimal to moderate details of main HP mentioned potions but you'd get equal or more details from a wiki page. The layout and formatting is pretty plain too. I think the main issue is at £12.94 it's just overpriced. I'm comparing it to something the Unofficial Harry Potter wizards spell book which I picked up in the Works for £5.99 down to £3 which has similar detail but nicer layout. I did want to try returning it but my son wants it for his collection... Okay but needs to be at least half the price.
