SATS
What are the scorings for the sats?
Like what score is average, or advanced or something? [I'm in 8th grade...] I was just wondering!

First of all I'd just like to say that the 8th grade is WAY too early to be worrying about the SAT. I've seen kids who think that starting early is a good idea, but all it does it turn them into nervous wrecks. But I'll answer your question anyway.
As a warning, you're not going to be able to follow what I'm about to say, because it's based on statistics (which I assume you have not learned). The important part starts after the sentence "So, since every standard deviation is roughly equal..."
So, here we go:
According to collegeboard.com, the average scores for the class of 2005 were:
Critical reading: 508
Math: 520
CollegeBoard also says that, generally speaking, only those in the a perfect score in a section is the 99th percentile for that section.
So, using the normal distribution curve found in statistics ([Link](Mouse over link to see full location)), you can draw these rough statistics:
2.5 standard deviations away from the mean takes you to the 98.75 percentile, which is close enough to 99th percentile, or a perfect score.
The differences between a perfect score and the mean scores for math and reading are:
800 - 508 = 292
800 - 520 = 280
So:
292/2.5 = 117 points per one standard deviation on critical reading
280/2.5 = 112 points per one standard deviation on math
According to the normal curve, from the mean:
+.5 standard deviations is 58th percentile
+1 standard deviation is 84.1 percentile.
+1.5 standard deviations is 90.9 percentile.
+2 standard deviations is 97.7 percentile.
+2.5 standard deviations is 98.75 percentile.
So, since every standard deviation is roughly equal to 117 points on reading and 112 points on math...
Critical reading:
508 + .5(117) = 567 = 58 percenile
508 + 1(117) = 625 = 84.1 percentile
508 + 1.5(117) = 684 = 90.9 percentile
508 + 2(117) = 742 = 97.7 percentile
508 + 2.5(117) = 800 = 98.75 percentile
Math:
520 + .5(112) = 576 = 58 percenile
520 + 1(112) = 632 = 84.1 percentile
520 + 1.5(112) = 688 = 90.9 percentile
520 + 2(112) = 744 = 97.7 percentile
520 + 2.5(112) = 800 = 98.75 percentile
So, what the hell did I just say? Sorry, I was bored and decided to do some math. But what I just did was useful to you.
Instead of telling you what I might think is a "good" score, or what other people might think, I gave you (roughly) the percentiles that a score on math and critical reading will get you. You can decide for yourself what percentile, and corresponding score, is "good" or "advanced."
