<p>Regarding the math, immediately after taking the test, did you feel confident or did you feel that the test was tricky?</p>
<p>If the former, you just need to avoid making silly mistakes. I am in a similar situation (will take Calc BC in junior year), and when I took the SAT in 9th grade, I felt fairly confident that I aced the math section, alas, 3 silly mistakes brought me down to a 720. Just make sure that you are meticulous with your calculations.</p>
<p>If the latter, I really don’t have much advice so follow someone else’s.</p>
<p>As for writing, I’m no essay expert but check out AcademicHacker’s thread. It seems that his format can get you at least a 10. What is likely weighing down your score, however, is the grammar. Take a look at this link:</p>

<p>And really focus on what it tells you. The grammar can be easily mastered when you know what to look for.</p>
<p>Best of luck.</p>
