I'm late to the party but Hogwarts probably teaches regular Muggle subjects. IT'S A BOOK SERIES ABOUT TEENS USING MAGIC AND LEARNING ABOUT MAGIC IN MAGIC CLASSES AND SINCE THERE IS A POTIONS CLASS IT MAKES SENSE THAT AT THE VERY LEAST THEY WOULD KNOW CHEMISTRY SO THEY DONT EXPLODE THE SCHOOL AND SINCE THEY HAVE TO WRITE ESSAYS FOR NEARLY EVERY CLASS OBVIOUSLY HOGWARTS HAS GRAMMAR CLASSES AND SINCE THE WIZARD WORLD HAS BANKS OBVIOUSLY THE STUDENTS ARE TAUGHT ECONOMICS AND SINCE THERE ARE OF LOT OF PLOT POINTS REVOLVING AROUND CORNELIUS FUDGE, MINISTER OF MAGIC, HOGWARTS PROBABLY HAS A POLISCI CLASS. SO MAYBE WHILE PEOPLE ARE CRAPPING ON HOGWARTS FOR nOt TeAcHiNg BaSiC kNoWlEdGe THEY ACTUALLY ARE BUT SINCE IT'S NEITHER MAGICAL OR VITAL TO THE PLOT, THAT AGAIN, HAS ROOTIN-TOOTIN MAGIC, THOSE CLASSES AREN'T SHOWN!!!!!! Don't @ me because I will die on this hill.
