Isn’t an average ACT of 20 a ridiculously low score? The high school I’m going to attend has an average ACT of 28, and it isn’t even consider a hard school whatsoever. Maybe you should go to the “hard new school” after all. I mean, if you aren’t challenged at your current school, I don’t see the point in you staying. Maybe it’s just my competitive mindset, as I always need somebody better than me so I can compete to become better than him. Good luck!
