You don't have to report to class, you can teach yourself. Self-study, first, download the outline from official website, and carefully implement each test center according to the outline, without any review omissions. Also, it is best to buy a sample paper to see how it is done and get familiar with the feeling of the exam questions.

Music theory and performance can't be tested together, because music theory and performance are completely different subjects, and the test dates can't be the same. ...

For example, if you give an example of music theory level 5 and performance level 4, then the date of the music theory test will definitely not coincide with the date of the performance test, so you can either take the music theory level 5 one day and take the music theory level 4 later, or vice versa. In short, it is impossible to take the exam on the same day.

Moreover, playing level 6 to level 8 requires a certificate of music theory level 5 to enter the exam.

If you think it is really difficult to teach yourself, then you can ask the teacher to help you. I wonder if you have taught yourself the piano. If you have a piano teacher, you can also ask ta to teach you music theory. If ta doesn't know music theory knowledge, it can only be said that ta is not a good teacher, because after all, Huang Wu's music theory is something that a piano professional should know, and it is all basic music theory knowledge.
