My D got 5 in AP Chem. CalcBC, and Physics C that got her skipped Chem1, Physics1, Calc1 and 2. She did struggle a little bit in Org Chem 1 & 2 and Calc3 in freshmen year and ended up with B to B+. She did great in Calc4 though. For Physics, she is going to take the Physics 2 in a CC this summer. If she does it well, she will finish all Physics requirement for engineering school. If not, she would not report the grade and take it again in the university.
