Hogwarts Magic and magical theory

Arithmancy class

"Arithmancy looks terrible," said Harry, picking up a very
complicated-looking number chart.
"Oh no, it's wonderful!" said Hermione earnestly. "It's my favorite subject!" (PA6)



Arithmancy is required for a career as a curse-breaker at Gringotts Wizarding Bank (OP29), so Bill Weasley would most likely have taken the subject for his O.W.L.s and N.E.W.T.s while at Hogwarts.
