it depends on the teacher, too. My daughter is not “mathy”. Senior year in high school, she was sure she was not meant to be in CalcBC and wanted to drop down to AB. Her math teacher called us and said, “she belongs in this class. If she works hard, I promise she’ll get at least an A- in the class and 5 on the AP test.” He was right. She pulled an A- in the class (by the skin of her teeth) and thought the AP exam was pretty easy. She scored a “5”. As did virtually all of the 30 or so kids in that CalcBC class, even those who got lower grades in the course. The teacher can make a huge difference.
