Teaching materials are not unified, but songs are unified. Test different songs at different levels and choose your own songs (if a teacher teaches you, you can ask the teacher to recommend which song is more suitable for you). Generally, you need to recite the spectrum, so you must prepare in advance. It's best not to pause in the middle. It's basically no problem to have that sense of fluency for the examiner to listen to (I think you are playing music instead of music).
