Hi, I'm Joon. I'm new to these forums. Sorry I posted this after my first post. :( My bad, didn't check my Email. So I know most of mechanics, and I'm good with most problems, I think. I just have to think a bit about most of them. I don't know theoretical, though. I'm only in 9th grade, after all. I'm really loving this community, been using it to help me with problems I don't get (as in, reading through similar problems), but I've decided to join, so that I can both ask for help and help other people. Cool meeting you, thanks for reading this, whoever's out there!!!!!
