The information you supplied doesn't say all that much. While your SAT scores are perfect, that isn't too far above average. Additionally, having perfect scores on the SAT II subject tests is not uncommon. The things that matter most for the admissions decision (since your test scores are fine) are your extracurricular activities. Even if they aren't all that special, its how you pursue them and the passion for learning that you show through them that makes them significant.
