We are doing the Periodic Table at home and this book was just apt. While, my daughter is only in primary grade, the concept eps the memory pegs are wonderful to learn. Yes, first time, I got the book with repeated pages. However got it returned and got the book to my satisfaction.
The book is with clear text and artfully done pictures. In-fact I am doing a series on Periodic table and use this book for reference. (check Periodic Castle with Jumpy Juveria on Sky Education TV - YouTube)
