More than one and a half million students took the ACT test this year, and only 638 of them achieved a perfect score.

St. Joseph's High School student Paul Anthony is one of those 638.

The ACT test averages the scores between the English, Math, Reading and Science portions of exam to get a composite score.

According to the Princeton Review, the national average is about 21. Anthony was among the less than one-percent who scored a perfect 36.
