AP Chemistry FRQ Calculator | Free Response Score Estimator

The FRQ Section at a Glance

Q1–Q3 (long-answer): up to 10 points each, 30 points total.
Q4–Q7 (short-answer): up to 4 points each, 16 points total.
Section total: 46 points, worth 50% of your overall AP score.
Materials allowed: a calculator, a periodic table, and the exam's equations/constants reference sheet are all permitted during this section only.

How FRQ Weighting Works

FRQ percentage = FRQ raw score ÷ 46

FRQ weighted contribution = FRQ percentage × 50

That weighted contribution combines with your MCQ weighted contribution to form your full estimated composite. Use the full AP Chemistry Score Calculator to see both sections together.

Interpreting Your FRQ Score

Your FRQ percentage alone doesn't predict your AP score, because MCQ and FRQ are each worth exactly half the total. A raw score of 29/46 (63.0%) contributes 31.5 of the 50 possible FRQ points — a strong MCQ result can offset a weaker FRQ result, and vice versa. Pair this result with your MCQ score in the full calculator for a complete estimate.

Worked Example

Here's a full FRQ calculation using the same numbers as this site's other worked examples, so you can check it against the full calculator's own worked example:

Step	Calculation	Result
FRQ raw score	7 + 6 + 5 + 3 + 3 + 2 + 3 (Q1–Q7)	29 / 46
FRQ percentage	29 ÷ 46	63.0%
FRQ weighted contribution	63.0% × 50	31.5 / 50

That 31.5 is exactly half of your final composite calculation — the other 50 points come entirely from your MCQ result. See the full AP Chemistry Score Calculator to add an MCQ score and get a complete estimate.

How Many FRQ Points Might You Need for Your Target Score?

Because MCQ and FRQ are each worth exactly 50 of the 100 composite points, there's no single FRQ number that guarantees a given AP score on its own — it depends on your MCQ performance too. That said, this site's score-target pages outline realistic MCQ/FRQ combinations for each goal, based on the same estimation model this calculator uses:

For a target of 5, example combinations include a solid FRQ (30+/46) paired with a very strong MCQ (55+/60), or an exceptional FRQ (38+/46) offsetting a slightly lower MCQ — see the full points-needed-for-a-5 guide for more combinations.
For a target of 4, example combinations include a solid FRQ (~28/46) with a solid MCQ (~40/60), or a stronger FRQ (30+/46) offsetting a moderate MCQ — see the points-needed-for-a-4 guide.
For a target of 3, example combinations include a balanced moderate performance (~20/46 FRQ with ~32/60 MCQ), or a stronger FRQ (24+/46) offsetting a lighter MCQ — see the points-needed-for-a-3 guide.

These are the same illustrative combinations shown on each score-target page, not a guaranteed cutoff — College Board does not publish an official raw-score table. See the full methodology.

FAQ

Can I calculate my FRQ score separately?

Yes -- this page is built for exactly that. Combine it with the MCQ calculator to see your full estimated score.

Does this use the official FRQ rubrics?

This tool does not grade your free responses; you (or a teacher) score each question against the official College Board rubric first, then enter the resulting points here.

What if I only have a combined FRQ total, not per-question scores?

Use "Enter total FRQ score" instead of the per-question mode -- the per-question mode needs all seven scores since it adds them up for you, but the total mode works with just the one combined number.

Can my FRQ score alone tell me my AP score?

No. FRQ is exactly half of the composite, so the same FRQ result can land at different final AP scores depending on MCQ performance — see our score-target pages for realistic MCQ/FRQ combinations at each target.

Do all 7 FRQ questions count equally?

No. The 3 long-answer questions are worth up to 10 points each (30 total), while the 4 short-answer questions are worth up to 4 points each (16 total). All 46 points combine into one FRQ raw score before weighting.
