<p>No matter how gifted you are in math, you need to have decent verbal skills. Assuming you got an 800 in math, you didn’t even break 600s on verbal and writing, which strongly suggests that you could benefit from finishing high school. </p>
<p>If your school has allowed you to take BC calc in 10th grade, then they have made all reasonable accomodations. They aren’t going to make an extra class for one students. You aren’t the first person to run up against this issue - one of my classmates finished BC calc in 5th grade, and somehow managed to survive with only graduating a year early. I believe he took computer courses and self-study to supplement his education.</p>
<p>Give yourself more time to prove yourself, and don’t even think about graduating more than a year early. Study for your SATs, and continue to show that you can do well in competitive classes. Harvard’s admissions director has encouraged students to take a gap year after high school to gain more maturity - I somehow doubt he favors kids who try to rush through high school before they are ready.</p>
