Students at Quince Orchard High School in Gaithersburg will get to keep their Advance Placement psychology exam scores, despite one student shooting a cellphone video at the testing site just before the exam started, officials said Tuesday.

The video, which was posted to Twitter on May 6, showed students preparing to start the exam, a No. 2 pencil, a blank answer sheet and something in plastic wrap that might have been the test, said Principal Carole Working. It did not show the test material.
