Currently, the AP courses cover 37 courses in 22 majors. Each exam is divided into two parts: the first part is multiple-choice questions, and the second part is free answer. Depending on the different subjects, the exam content of each course will vary in difficulty. Candidates can choose the exam subjects according to their actual needs, and apply to the US Educational Testing Service (ETS). Students can receive their transcripts before the end of June. Therefore, for students who are aspiring to enter prestigious American universities, it's essential to make reasonable plans and prepare scientifically based on your own situation.
