Just wanted to reply back and let this community know that my D26 did end up with an A in Calc AB at the end of the sophomore year. She was good at the concepts, just needed more practice which she did and ended up with an A. She probably also got a 5 in her AP test but those results will be known only in a few months.
She will be taking Calc BC in her junior year.
She does enjoy math, even though her first semester of sophomore year ended up with a C on Calc AB. Her college counselor is saying that she should not apply for STEM courses in college as the C will play a big role. But she is confused, as she like the STEM line.
Not sure what is the right path forward, but sharing with the group here to get there thoughts as well.
