I skipped the exam and signed up for a class at Xinglian Music Postgraduate Entrance Examination. I signed up relatively early and started preparing for the exam earlier. I was afraid that I would be late and not be able to keep up with others. I think signing up for the class is cost-effective. It is relatively high, which will save a lot of time and give you a lot of experience and skills in preparing for the exam. If it is a cross-examination, it will definitely be more difficult to learn on your own.
