Very good book. It covers science from 5th std to 12th std. The narration is child-friendly and much better than traditional textbooks. It keeps the kid engaged with explanation and questions.Good examples for the basics.
Timely arrival. Excellent quality product. Serves the purpose of catching up 10-12 year old kids with what has been covered so far at school. Helps as a refresher for adults too. Totally worth the price.
