Basic Chivalry is an elective class taken by both Carlos and Jay for fifth period. It is most likely an elective offered only to males. In Mal's Spellbook, Jay mentioned that a plate with a knife, two spoons and two forks were placed in front of them and they did not know what to do with them. Based on the incivility of the villains on the Isle of the Lost, it is not unbelievable.
