New Order

Good morning, I apologize in advance if I have posted in the wrong section.

I have tried searching around but my ideas are even more confused. I am a private student who is supposed to take the admission exam for the three-year degree program, but I cannot clear up these doubts:

-I already attend another university, can I still enter the conservatory?

-once admitted, how much would I have to pay annually, on average?

I hope someone can help me, thanks in advance.
