How AP Chemistry Scores Are Calculated

The AP Chemistry exam has two equally weighted sections: 60 multiple-choice questions and 7 free-response questions (3 long and 4 short). Raw points from each section are scaled to 50 points each, then combined into a composite score out of 100.

Composite Score Formula

$$\text{Composite} = \text{MCQ} \times \frac{50}{60} + \text{FRQ} \times \frac{50}{46}$$
