<p>I don't know my grades, but I do well in everything pretty much. I'm a high school freshman, and I have no idea how to calculate GPA. I took an honors bio course (the regents one, not AP) last year and didn't do so great; I got only a 92. What kind of GPA (with and without weight) are we talking about? </p>
<p>Also, what are percentiles when talking about the SAT's? I only know the 2400 one...</p>
