<p>Unless you’re a genius/borderline (read: not taking advice from CC), there’s really no reason to do so. The most I would recommend would be taking Alg II/Pre-calc freshman year and then hitting some geometry and early calculus over the summer before taking BC sophomore year. There are some important trig concepts and general mathematical experience that will help you out in those courses.</p>
<p>In reality, though, this may hurt you more than it helps you. You likely won’t apply calculus and subsequent classes in differential equations and linear algebra until your 2nd and 3rd year of college. That leaves a 3-4 year gap between when you learn the math and when you apply it, which could negatively affect your performance. Unless you’re graduating from HS in 2-3 years and starting engineering courses in your freshman year, in which case you’re probably should seek professional counseling, there’s really no reason to skip three math courses.</p>
