My first mock exam at Skeisvang Music High School... I need some help.

#1
So, my first mock exam at Skeisvang Music High School (or whatever you want to call a music high school kinda thing) is next week. I HAVE to play two songs on the guitar, one on the piano, and one on vocals. On the guitar, I'm going to play YYZ by Rush, for sure. I also have practiced a lot on Am I Evil by Diamond Head and I have also thought of Headless AND The Headless Horseman (I'm going to combine those two songs) by Joe Satriani, but I'm not sure! If I'm going to play Am I Evil, I'm going to play guitar and sing, so I don't have to sing another song. Which shows the most skills? Am I Evil w/solo (ofc) and singing while playing, or Headless & The Headless Horseman which mainly consists of tapping and rythm?

Also, I need a song for piano. I'm a beginner, but I want a song that is respectable for my taste in music (check my profile for that)

I have been stressing a lot, and after this weekend I have to practice with a band. So I have to put a lot of work in finding someone who has time to play with me on my mock exam.

Thank you.

well i think for piano maybe Charades by Serj Tankian, it doesnt sound to challenging and is a nice little song

I have decided a song on the piano now. I don't know who wrote it, but my piano teacher suggested it to me. And it's pretty nice. A little classical though, but on the piano, I like it. It's called "Preludium."

I still need some advice of which song would be best to pick for me on the guitar.
