This is from that link: "AP Calculus AB focuses on topics that are taught in the college-equivalent first-semester calculus class. AP Calculus BC focuses on topics covered in both first- and second-semester calculus classes."
It's not unreasonable that some schools, for some kids, would have them take the college-equivalent first-semester calculus class one year, and the second year take a class that covers the second-semester calculus class. So after the first year, they'd be prepared for the AB exam, and after the second year they'd be prepared for the BC exam.
I'm not sure why people are so hung up on this. There are a ton of different math pathways from pre-algebra to.... wherever a kid ends, and schools handle those in all different ways for different kids.
