<p>Calculus III is not particularly impressive unless you are a freshman. Most strong math and science students at schools like Andover, Exeter, and TJHSST—even most magnet schools for that matter—will have done that plus linear algebra by the end of tenth grade. If that’s the best you’ve got and are interested in STEM, you’re behind other math and science students heading to Ivy League and similarly selective schools, especially compared to students at HYPMS, Yale a little less so, though.</p>
