Studying art is generally more costly, and studying one is generally a bit less costly, which we can see from what happens when you take a university exam. Generally speaking, the students who take the art university need to do a lot of work in the early stage, such as studying some art subjects, the tuition fee itself will be very high, while medical students just need to learn their own homework can be good. So it doesn't require much preparation and even less money.
Generally speaking, art students need to prepare too many things, so they will spend a little more, which is also a normal phenomenon. As for medical students, they usually study mainly on-campus, so they just need to follow their teachers to learn good undergraduate knowledge. For the arts people need to communicate with the teacher, need to learn with the teacher in particular, for example, also need to buy a piano. Also need to buy some music equipment, these are additional expenses, so the cost of students studying for the arts will be very high.
