The Music Department of Normal University does not require Grade 10, but general graduates require a minimum of Grade 6. As for you saying that you want to take the 10 grade, it's urgent. Even if you pass 10, you will only know one song with 10. It is really important to have a solid foundation, so as to learn the piano well, play the piano well and really learn something.
I am a music major in Normal University. I suggest you don't ask music students to learn piano. It's better to go directly to the university teacher. First of all, the level is definitely higher, and the teaching experience is at least richer than that of students. Even if you really want to take the exam, the teacher knows the exam requirements better than the students.
