Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
I really appreciate the effort of team Kutuki. All the videos are very knowledgeable and linked to the culture of India. These are much better than other kids videos. Videos related to phonics are also very nice. Best of luck for your future plans.
