How we convert raw points to scaled scores
- Multiple‑choice: 60 questions, counts for 50 % of composite.
- Free‑response: 7 questions (3 long, 4 short) worth 50 % total.
- Composite scaled to 100 points (MCQ 50, FRQ 50). We average the last three curves to map composite → 5‑point scale.
2025 raw‑score → scaled‑score chart (estimate)
| Composite (0‑100) | Predicted AP Score |
|---|---|
| 72 – 100 | 5 |
| 58 – 71 | 4 |
| 42 – 57 | 3 |
| 27 – 41 | 2 |
| 0 – 26 | 1 |
Cut‑offs based on College Board score distributions (2022‑2024); expect minor shifts each year.
Study tips to lock in a 5
- Memorise fundamental constants & common polyatomic ions for quick recall.
- Practice stoichiometry setups—dimensional analysis earns easy MCQ points.
- For FRQs, always include units and state whether answers are justified with calculations or reasoning.
- Use particle diagrams to illustrate equilibrium and acid–base buffers for explanation points.
Frequently Asked Questions
Is guessing penalised on the MCQ?
No. Select an answer for every question—there’s no deduction for wrong choices.
How many significant figures should I use?
Use proper sig‑figs in your final answer (usually 3) and keep at least 1 extra during calculations.
How accurate is this calculator?
Within ±1 score point for most students, based on recent curves.
