As a Quaver student, you have access to a virtual "currency" called QuaverNotes. You can use QuaverNotes to purchase virtual goods for your avatar (clothes, instruments, etc.). Once you have them, they do not expire!
While there is not a way to "earn" QuaverNotes on the student site, Quaver offers a monthly code for 100 QuaverNotes which I will provide to you! Make sure you check here often to see the current codes and grab your QNotes!
