Calc AB vs. Calc BC For SCEA applicant

I am debating which I should take next year and am wondering if it would hurt me a lot if I took Calc AB (what I’m currently signed up for) instead of BC. I am leaning towards AB due to the rest of my courseload and extracurriculars, but would consider switching if it would hurt my application.
I am applying to Harvard in the fall and ideally would do a History of Science concentration, if that makes a difference. Also, I have always taken the most difficult courses at my school, with the exception of taking AP Physics 1 this year instead of AP Physics 1&2 combined. (Hopefully this won’t hurt too much… Also slightly worried about this)
Anyone have an opinion on taking AB or BC and if it would hurt my application or not?

There was an article in the Crimson a year or so ago. If I find it, I’ll link it in. Basically, one of the questions it asked the freshman class was what the highest math class they had prior to Harvard. IIRC, AB and BC were close to equal. So I’d say it makes no difference, assuming that your GC marks your schedule as “most rigorous.”

Wow okay thanks so much! @skieurope
