I personally think that this is a rather good book as the analysis about the intelligence level is trhorogh and clear. Also, the factors used to determine intelligence are clearly stated and explanied. However, I think that creativity and other quotients like emotional quotient should be quoted in the book more thoroughly in order to give a more detailed explanation on intelligence. Howver, the overall effect created in the book is very interesting and the book gives a very deep insight on both intelligence and personality for everyone.
