Grammar

Not withstanding Remedial Goodness 101, Grammar is the fifth period class for Mal (according to Mal's Diary) and the third period class for Evie and Jay. It is a class requirement at Auradon Prep. It is unknown which class number it is for Carlos, but considering that Mal, Evie and Jay all take Grammar, one can determine this a core requirement and as such would be on Carlos' class list. This class is Princess Audrey's least favorite class[1].
