Estimated from published section weights; the official 1–5 cutoffs are set each year and not released by College Board.
The AP Chemistry exam splits evenly between multiple choice and free response — each worth 50% of your score. This calculator scales your raw points the way the College Board does, adds them into a composite out of 100, and maps that to a predicted 1–5 using cutoffs estimated from recent released exams.
How AP Chemistry is scored
Your 60 multiple-choice questions are scaled to 50 points, and your seven free-response questions (46 raw points) are scaled to the other 50. Together they form a composite out of 100.
College Board doesn't publish official cut scores, and they shift a little each year. These thresholds reflect commonly cited estimates from recent released exams and are what this calculator uses.

Worked example
45 of 60 multiple choice, plus 20 long and 12 short free-response points (32 of 46):
MC = (45 ÷ 60) × 50
37.5
FRQ = (32 ÷ 46) × 50
34.8
Composite = 37.5 + 34.8
72.3 → score of 5
Frequently asked questions
How many points do I need for a 5 in AP Chemistry?
Roughly 68 out of 100 composite on the estimates here — about two-thirds of the available points across both sections. The exact line moves slightly each year.
Is there a guessing penalty?
No. There's no penalty for wrong multiple-choice answers, so always answer every question.
How accurate is this prediction?
The composite is calculated with the official section weights, so it's precise. The 1–5 mapping is an estimate, because College Board sets and doesn't publish the yearly cutoffs.
Can I use a calculator on the exam?
Yes — a scientific or graphing calculator is allowed on both sections of the current AP Chemistry exam.
Unofficial estimate for study planning. Composite uses official section weights; the 1–5 cutoffs are estimated from recent released exams and are not published by the College Board, so your real result may differ.
