Audition in Erwin Gutawa's Studio

My sister's drum teacher told me that there's an audition in Erwin Gutawa Studio for 8-13 years old kids. They scheduled me today, and this is my first experience. I played Mozart and Beethoven. At first, I didn't feel nervous, but in the middle of the audition, I felt a little nervous. I made several mistakes, but I hope that's okay. After the audition, everything went back to normal. Here's some posters that I saw in the studio.
