Harry’s remark about switching to MMA clearly had surprised Hermione; but now she stopped to think. "Fifth year at Hogwarts, History of Magic will be worthless, DADA will be worthless, and the only reason Potions will maybe not be worthless is because Harry killed Snape. Slytherins can do as they please, this won’t change, and Muggle-borns like me again will get no help and no protection from the professors. Also, every day in Hogwarts is a day when I’m getting no education in nonmagical subjects."
