You can skip the piano test.

You can skip a level, but you are not encouraged to skip the exam. You should take it based on your actual ability. It is not just to get a certificate, but mainly to test and train students and test the teacher's level from one side.

The piano is just a musical instrument. Grades are just artificial standards (that’s why there are amateur and professional grades and internal standards of each conservatory). Choosing a piano as an instrument means that you are destined to go a long and hard way in mastering its unique playing techniques, skills and harmonic knowledge that are higher than those required by any other instrument.
