help with pre-algebra?

I am doing really bad in pre-algebra. I mean I do all my homework and I understand what's going on in class and stuff. I ask questions when I don't understand. Also I ask for help when I need it. The only problem is homework is 20% of my grade. I have 100% in homework this quarter. I have problems with tests and quizzes. I do really bad on tests and quizzes. It's like I would study the night before and when it was test time I would forget everything. I am about to cry because my parents are reallly worried about my math grade. I don't want to go to math 8 next year because I'm not stupid. I want to go into algebra. Please someone tell me what should I do.

Is there a lesson to be learned from Star Trek?

I know this might sound crazy, but in the Star Trek series the Earth is such a better place to live. Also if you look at their history it kind of reflects what's currently going on in real life wars, poverty, racism and etc. But for some reason space exploration and discovering other intelligent beings united the people of Earth. All that petty stuff I mentioned really doesn't exist in Star Trek, so is there a possiblity that something like that could occur in real life.

Question about our distance from the sun.?

Why is it that there is such an extreme temperature change when you move only 500 miles or so north or south of the equator? I mean, if you think about it, that 500 miles is a TINY fraction of how far away from the sun we really are. If you were to move the earth 100 miles closer or further away from the sun would we not be able to survive on it? I don't know much about science - unfortunately, in my highschool you passed if you knew how to read or were a vital component to the football/basketball team.
