RCM Level 4 exam

This is my first time taking an exam with RCM. I'm no really sure what to expect and I'm really nervous. It's in a few days and I've been practicing my pieces like crazy and watching yt vids on the musicianship and ear training stuff. I'm kinda worried about the scales and playback tho and I don't want to look dumb in front of the instructors. And I know I won't lose a lot of points with those things but I still want to do good. Any tips?
