Studying and brains

Boy, the homework has stickied back! I had to do math-which can take me awhile, since I struggle majorly in math, but today I was doing great on it-studying for a geography test-I'm pretty good on that too-and Science, and I didn't have much left of that.
I have a friend who takes all advance classes (including gemotrermy, and she's a fish!), Chinese School on Sundays, and her parents get mad at her, and ground her if she gets anything lower then a 95. She's been all upset this week cuz she got a 90 on a math test! Not to mention her parents got mad at her for it! I would do anything to get a 90 on a math test! But she acts like it's a bad thing! It's no wounder this girl is staying up till 11:00 P.M. doing her homework, and doesn't have any hobbies outside of video games! This is really unhealthy-I mean, aiming for high As is a good thing, but parents pressuring their kids, which makes them pressure themselves, kills the imagination! How are they supposed to live normal teenage lives when they get all this pressure and stress? I know you want your kids to do well, but parents, remember that we are young here, and can take only certain amounts of stress here!
My next topic is brains. I know this sounds weird but the other night I was thinking that I would really like to study brains. See I'm dyslexic, and I have had some friends who were special needs so I've always wounder what makes a "normal" brain. I mean how do you know which Brain is "normal"? Or does nobody have a "normal" brain. And what makes the right side of my brain (which is your creative side) bigger then the left side (your learning/school side) which makes you dyslexic? Why isn't it the left side bigger then the right? Why is it the right side bigger then the left? And what do you have to have a "normal" brain, if their such a thing? What makes us normal, and what makes us weird, and an outcast? Or are we all weird or all normal? Or are we neither?
