Wow...I've had a very similar experience! My IQ was in an average range, yet I was able to increase all of my MSA scores if they did need increasing, and I, too, truly feel that my IQ is higher than a 97, as do my mom's numerous friends. I also think your son is gifted, and in my opinion, IQ scores don't thoroughly test your child on a multitude of areas: they only seem to care about critical thinking. It's great that he improved, though! ^^
