My DS took a similar math path (he got in Caltech and Stanford intended major Chem E). He took AP Calc BC in Junior year, then for senior year instead of taking AP Stats, he took Differential Equations at a CC. By taking AP stats and getting A in it, her GPA will go up, but colleges look at the rigor of the curriculum, so taking DE at a CC would be a better choice. When his underclassman friend asked for his advice about math path he told them don’t take AP Stats.
BTW I hope she’ll ace her PSAT in her Junior year and will become NMSF, even though the title doesn’t add much to her college app, most of, if not all of her competitors will be NMSF and/or NMF.
I don’t see any Electives, is the Spanish class elective? Other than Spanish she’s not taking any elective? Highly selective colleges don’t want students who only study and show no interest in other things. My son took many electives which helped him to reflect his experiences in his essays. If she loves Math, she should consider tutoring her peers at school. Colleges want to see students who give back to their own school. Join NHS or leadership club and start a math tutoring session. Join in Mathlete club (if there isn’t one create the club) and participate in a competition. There are so many things she can do outside of the classes. Good luck.
