Advanced Placement (AP) Exams are subject-specific assessments administered by the College Board. They test knowledge and skills in individual subjects, such as Calculus, Physics, Chemistry, Computer Science and Economics.
The SAT is a standardised test used by participating universities to assess college-readiness skills, particularly in Reading and Writing and Mathematics. The PSAT is a related assessment used for practice and, for eligible students in the US, certain scholarship-related purposes.
The key difference is that AP Exams assess subject knowledge, whereas the SAT assesses broader academic skills. Neither automatically replaces the other, and requirements vary by university.
