The most important thing for music postgraduate entrance examination is whether one's music literacy and professional knowledge are up to standard. If it's some performance, it's relatively difficult. Non-performance comparison will be easier. Then, it depends on whether you have enough time. If you are only a freshman or sophomore, you can consider taking the postgraduate entrance examination yourself. It's best to have some buffer time. Theoretical knowledge is relatively easy, and you need to master some professional knowledge. Non-professional students may be generally overconfident, but your professional teacher sees you too clearly. You need to adjust yourself and ask for advice with an open mind. You need to work harder to get the approval of the postgraduate teachers, and you need to have a clear understanding of your own abilities. There is also family conditions. If you want to study music as a graduate student, you may not know some music if you are confined to China, but the cost of going abroad is high and you may not be able to afford it. It depends on family conditions. Finally, I hope you can have your own satisfactory answer.
