The good score of 99 points in the fifth grade exam shows that the child has mastered the corresponding mathematics knowledge in this age group and has excellent problem-solving ability. From this point of view, it can be considered that children have a high level of intelligence in mathematics. However, children's intelligence can't be measured only by a single achievement, but also by their performance in other disciplines and activities, as well as other qualities and characteristics that children have. Therefore, we can't simply think that a child's high score in the math exam means high intelligence.
