Napoleon's noble, moderately affluent background afforded him greater opportunities to study than were available to a typical Corsican of the time. In January 1779, he was enrolled at a religious school in Autun. In May, he was admitted to a military academy at Brienne-le-Château. His first language was Corsican, and he always spoke French with a marked Corsican accent and never learned to spell French properly. He was teased by other students for his accent and applied himself to reading. An examiner observed that Napoleon "has always been distinguished for his application in mathematics. He is fairly well acquainted with history and geography... This boy would make an excellent sailor."[note 3]
