make my lowest grade a C
Uh. No offense or anything, but that's hardly what I'd call a good grade. Not to show off, but my lowest grade is a 98, and I've been accepted to take the SATs (simirally, I'm thirteen). A C isn't good at all; you can do much better than that. (And is it just me, or was that post just an excuse to show off your grades?)
And didn't we settle this? He's supposed to think smarter than his age, he's a character.
Also, I've read the story over. I think it's kind of adorable to see how the writing got from good to great, and now I think I know what you mean when you say that you want to rewrite them. Not that they're bad, (better than what I can write, at least), but they can definitly be improved.
(No proofreading. Sorry.)
