AIME(this math test for olympic team, did I type it right?) had higher score than my son had and some even qulified. My son is known for doing things fast. he usually spend half of time other kids need to finish same task. When his right arm broken, in a test tearcher said time is over and every kid in the class said not enough time because my son wasn't finish yet. comp sci class may just need a little more time than other classes.
