Kwasi Enin of Shirley began hearing from the schools on March 27.
The William Floyd High School senior said that he couldn't believe it when "the yesses kept coming."
Brown, Columbia, Cornell, Dartmouth, Harvard, Princeton, Yale and the University of Pennsylvania all said yes.
Kwasi says he thought, "this can't be happening."
He scored 2,250 out of 2,400 on the SAT. That places him in the 99th percentile for all students taking the exam.
