AP Calc BC Score Calculator

Estimate your AP Calculus BC score in minutes. Enter your MCQ correct count and FRQ points to see your likely 1–5 range. You can also enter AB‑only totals for a rough AB Subscore estimate. This tool is unofficial and for practice only. Explore more tools on free calculators on CalculatorBolt.

How it works

AP Calc BC has 45 MCQs (no‑calc + calc parts) and 6 FRQs (typically 9 points each).

By default, MCQ and FRQ each contribute 50% of the estimate. You can edit weights and the curve in Advanced.

Formula: weighted raw % = (MCQ% × MCQ_weight) + (FRQ% × FRQ_weight), then we map it to a 1–5 score with adjustable bands. Real AP curves vary each year.

AB Subscore: Colleges sometimes view an AB subscore on the BC exam. Our optional “AB Subscore” section provides a rough estimate using AB‑topic subsets. It’s only an approximation.

Inputs explained

  • MCQ: correct answers out of 45 (edit total if your practice differs).
  • FRQ: enter points for Q1–Q6 (0–9 each). The tool totals them (default 54).
  • Advanced: adjust section weights, curve bands, and FRQ/AB totals to match a teacher‑provided curve.

Example

“MCQ 32/45 → 71.1%. FRQs: 7+6+6+6+5+7 = 37/54 → 68.5%.”

Weighted raw ≈ (0.711×0.50) + (0.685×0.50) = 0.698 → 69.8%

Estimated score ≈ 3 (with default bands)

Optional AB Subscore example (if provided):

AB MCQ 21/28 → 75.0%; AB FRQ 19/27 → 70.4% → AB weighted ≈ 72.7% → ≈ 4 (approximate)

Tips & notes

  • Curves and rubrics change. Use this as a planning guide, not a prediction.
  • A few FRQ points can move the estimate—show steps, justify reasoning, label graphs.
  • Practice both non‑calculator and calculator MCQs; be fluent with derivative/integral rules and series topics.
  • If your teacher shares a curve, edit bands in Advanced to match it.

FAQs

It’s an approximation using typical weights and a simple banded curve. Real AP scoring varies yearly. Use this for practice only.

Yes. Open Advanced to edit section weights, score bands, and totals. Click “Reset to defaults” anytime.

We include an optional, rough AB subscore estimate using AB‑topic subsets. Official subscores use specific AB‑only items, so treat this as a guide.

Edit the FRQ total in Advanced or adjust per‑question scores accordingly.
