<p>with all due respect i beg to differ from OperDad…I took AB as a sophomore and am currently taking BC as a junior. yes, BC does cover a lot of the same topics as AB does, but it goes through them much much faster. in addition, the extra BC topics covered are significantly MORE difficult than the AB topics (stuff like series and sequences, polar, integration by parts, partial fractions, etc etc)
take AB to get a good foundation for BC, or you will find yourself struggling with the topics because they’re taught quickly and superficially, since teachers assume you’ve already learned the stuff in AB. a lot of kids in my class who hadnt taken AB dropped out or are failing BC because the level is completely different.
of course it depends on your school/teacher/etc…but i would definitely recommend taking AB first. besides, if your daughter is already in HPrecalc as a soph, she’s at a much more advanced level in math than most sophomores. why rush and take BC junior year if you can do AB/BC junior/senior year?</p>
