Our child unfortunately got B’s in his pre-calculus class and was therefore disqualified to take AP calc BC in his junior year. He is considering taking AP calc AB at school, concurrently take AP calc BC online (and take the AP calc BC test in May), and then he can take multi-var in his senior year (also outside, because his high school does not accept his calc BC credit from an outside online class). Would it look bad to UC admissions that he does not take calc BC at his own high school? He is a die-hard engineering major.
