Disclaimer: Estimates only—final scores depend on College Board scaling.
How we convert raw points to scaled scores
- Multiple‑choice: 35 questions, counts for 50 % of the composite.
- Free‑response: 3 questions (1 laboratory, 1 qualitative/quantitative translation, 1 paragraph argument) worth 50 %.
- Composite scaled to 90 points (MCQ 45, FRQ 45). We average the last three curves to map composite → 5‑point scale.
2025 raw‑score → scaled‑score chart (estimate)
| Composite (0‑90) | Predicted AP Score |
|---|---|
| 53 – 90 | 5 |
| 39 – 52 | 4 |
| 32 – 38 | 3 |
| 20 – 31 | 2 |
| 0 – 19 | 1 |
Cut‑offs based on College Board distributions (2022‑2024); expect small annual shifts.
Study tips to earn a 5
- Know Maxwell’s equations in integral form—surface & line integrals appear in FRQs.
- Practise drawing field diagrams for point charges, dipoles, and solenoids; label direction.
- Memorise key relationships: C = Q/V, U = ½CV², Φ = BAcosθ, ℰ = −dΦ/dt.
- For FRQs, show variable substitutions and include units for every calculated value.
Frequently Asked Questions
Is guessing penalised on the MCQ?
