Well, 99 percentile on math for five years old is not kind of cry for help, situation might change dramatically for the next two years. For example, my DS10 was an early learner and tested above 90 percentile for 4th grade math at age 5. OTOH, my DS7 was busy designing spacecrafts and building complex models. He had little interest in reading&math and was well below 50 percentile at age 5. But he made a couple of surprise leaps once he started reading and arithmetic in first grade, and now tested above 95 percentile. Both of them were in the regular school without gifted class option for K to 2.
