A 17 year-old boy from Florida was stunned this week when he learned that he had gotten a 1600 score on his SATs.

Jacob Harrison had set a goal of getting a 1550 on the exam, but he was able to surpass this score with a perfect one, much to his surprise.

“I was shocked, I showed my friend because I was walking to school,” said Jacob, a junior at Largo High School in Largo, Florida. “We both kind of freaked out for a second and then ran to class.”

The SATs are known for being an incredibly difficult exam that is split into two sections: Evidence-Based Reading and Writing, and Math. Reports state that last year, less than one percent of the 2.1 million people who took the exam walked away with a score between 1400 and 1600. College Board Media Relations Associate Director Jaslee Carayol explained that they do not track the number of perfect scores that come in on the test.

Though Jacob had studied and taken practice tests, he is involved in so many extracurricular activities that finding time to prepare for it was difficult. The young man is involved in the Math Honor Society, the Science Olympiad team and the wrestling and swimming teams.

“I was just trying to focus, but I kept getting distracted,” Jacob said, explaining why his perfect score surprised him so much.

His mother Sherri Harrison was also stunned by his score.

“I thought he was teasing me,” she said. “When I saw the 1600 and realized his name was on his College Board account and saw his name on it, I realized it was true.”
