I don't deny that the IQ index represents whether a child is smart or not. I don't think we should look at a child by it. No matter how high the IQ is, the child won't learn well. What's the use of intelligence in the right way? What is genius? Genius is 99% sweat and 1% IQ. I suggest this friend that you don't believe in IQ index and take more experiences to cultivate the child's ability to do things seriously and practically! ~ personal opinion
