I was already in college at the age of 17, so being at a college reading and writing level at that age really does not impress me one bit. In fact, I'd be a bit worried if you weren't. ANY high school senior should be at college reading and writing level if they plan to go on to any sort of higher education. If you haven't achieved it by now, the few months between now and graduation aren't really going to improve it that much.
So stop trying to impress everyone with how smart you are; you'll get along much better. Not just here, but with the rest of the adult world as well. That's a hint for when you hit court, by the way.
You are accused of a crime. You need an attorney. The best advice anyone can give you is to get one.
