<p>At my kids’ high school, the typical math sequence is Algebra 2 in 9th (having completed Algebra 1 in 7/8), Geometry in 10th, Precalculus in 11th and Calculus (either college prep or AP AB Calc) in 12th. The super advanced honors track does Algebra 2 in 8th grade. The regular honors track does AP BC Calc in 12th and honors versions of the other courses in 9-11. Calc BC is a one year course at our HS, unlike some schools that do AB one year and BC the next. Unless you start in honors, you can’t move into honors. I’m sure that varies from school to school, so check with your high school for what is possible in their curriculum. My D1 followed the typical path through 11th grade, then decided she wanted to take AP Stats as a senior. But she knew she should have Calc, too, so she took Calc 1 at our local community college the summer between junior and senior years. </p>
<p>She is an Economics major (not at Chicago or MIT or equivalent) and is doing fine despite having started college with “only” Calc 1 under her belt. She will finish with a double major in Econ and Math and is none the worse for having followed her HS’s “typical” math track. FWIW, in college she’s had Calc 2 and 3, Linear Algebra, Differential Equations and Theory of Probability, and math-wise she still needs to do Mathematical Statistics, Math Economics, Econometrics and Math Analysis. It’s very do-able. She is on the more quantitative track; nothing beyond Calculus for Business and Social Studies majors is required for the basic Econ major, although as much math as possible is recommended.</p>
