OYSTER BAY - Some students at Oyster Bay High School were forced today to retake Advanced Placement (AP) exams after the original tests were voided or invalidated over alleged seating policy violations.

A spokesman for Educational Testing Services, which administers the exams, told News 12 Long Island that students were allowed to sit across from each other, which is against the rules.

The College Board was tipped off about the seating arrangement by a student who placed an anonymous call. The school then provided its seating chart to the board, which went on to void four of the AP exams.

In a statement, Oyster Bay High School Principal Dennis O'Hara said that after a lengthy conversation with the school administration and the College Board, it became clear the only option was for students to retake the exam.

Three of the voided AP exams were administered today. The AP physics exam will be given Friday.
