There are many different types of erhu exams, which are mainly organized by different organizers, such as the State Education Commission and the China Musicians Association, but most of them are held once a year. There are skipping classes in erhu exams, but different erhu exams organized by different departments have different ways of skipping classes. For example, the China Musicians' Association can only skip classes if it reaches Band 6. There are also some grades that can only jump to Grade 6 or below Grade 8. It will take three years at the earliest to reach 10, but it is not realistic for beginners, so it is necessary to take the exam step by step. So keep the speed of taking the exam once a year. If you can skip it once or twice, you will get the erhu 10 grade in 8 to 10 years.
