AP Chemistry

Course Overview 课程介绍

AP 化学相当于大学普通化学一学年，9 单元，5 分制，4 分以上可换学分。

AP Chemistry, administered by the College Board, is equivalent to a full-year university General Chemistry course. Organized around nine units and Big Ideas, it covers atomic structure, bonding, intermolecular forces, reactions, kinetics, thermochemistry, equilibrium, acids/bases and electrochemistry, with strong emphasis on quantitative analysis and inquiry-based lab work.

Credit Transfer 学分转换与衔接

4/5 分常换算大学普通化学（含实验），医学预科常作免修前置。

AP Chemistry is scored 1–5; most US colleges grant credit for 4 or 5, typically mapping to one or two semesters of General Chemistry (with lab). STEM and pre-med programs often accept a 4/5 as a prerequisite waiver. Policies vary by institution.
