AP Physics 1 Score Calculator 2026
Enter your section scores for AP Physics 1: Algebra-Based to estimate your 1–5 AP score.
Estimate. The College Board does not publish composite cutoffs, so these lines are reconstructed from released exams and third-party curves. Treat it as a prediction, not a guarantee.
AP Physics 1 was redesigned for 2025, and the changes matter. Fluids moved over from Physics 2 as a new unit, the old multi-select multiple choice is gone, and the free response now comes in four fixed types. The exam rewards written reasoning as much as algebra, and the 2025 curve was unusually friendly: the pass rate jumped from 47% to 66%, the biggest one-year gain of any AP exam.
Inside the AP Physics 1 exam
Three hours. Section I is 40 multiple-choice questions in 80 minutes (50%), all now single-answer with four choices. Section II is four free responses in 100 minutes (50%), one of each type: Mathematical Routines, Translation Between Representations, Experimental Design and Analysis, and Qualitative/Quantitative Translation, worth 10, 12, 10, and 8 points. Expect a fluids question, since the new Unit 8 is 10 to 15% of the exam.
How the AP Physics 1 score is calculated
AP Physics 1: Algebra-Based combines these sections into one composite out of 100:
- Multiple choice: out of 40, weighted 50% of the composite.
- Free response: out of 40, weighted 50% of the composite.
Estimated score ranges
- 5: composite ≈ 70–100
- 4: composite ≈ 54–69
- 3: composite ≈ 40–53
- 2: composite ≈ 25–39
- 1: composite below 25
These ranges are estimates from past released exams. Use them to see how close you are to the next score, not as an official guarantee.
How to squeeze out more points
- Write the reasoning, not just the formula. The newer free-response types reward a clear explanation of why, so a sentence connecting your equation to the physics often earns more than the final number.
- Drill the experimental design question. One free response is always about designing or analyzing an experiment: naming variables, describing a procedure, reading data. Those are predictable points if you practice them.
- Know fluids cold. Buoyancy and Archimedes' principle, plus Bernoulli and the continuity equation (faster flow in a narrower pipe), show up often now that fluids is a full unit.
- Carry units and define your symbols. Algebra-based or not, dropped units and undefined variables cost easy points across every question.
Where students lose points
- Giving a number with no explanation. The redesigned free responses are built around reasoning, so an unjustified answer leaves most of the points on the table.
- Skipping the fluids unit. It used to live in Physics 2, so older review books underweight it, but it's now 10 to 15% of the exam.
- Rushing the experimental design question. Vague procedures like "measure it and record" don't earn the design points; name the variables and the steps.
- Studying from pre-2025 practice tests. They have multi-select questions and a different free-response style that no longer match the exam.
A worked example
On the 2025 curve a composite near 70 of 100 landed a 5, with a 3 around 40, a notably generous line. The two sections each count for half, so 30 of 40 multiple choice plus solid free-response reasoning is well into 5 territory. Enter your section scores above to see where you fall.

Frequently asked questions
- How is the AP Physics 1 exam scored?
- Each section is weighted into a composite out of 100: Multiple choice out of 40 (50%); Free response out of 40 (50%). The composite then maps to a 1–5 score.
- What composite do I need for a 5 on AP Physics 1?
- On our estimated curve, roughly 70+ (out of 100) is a 5, 54+ is a 4, 40+ is a 3, and 25+ is a 2. These shift slightly every year.
- Is this the official AP curve?
- No. The College Board equates each administration to keep scores comparable across years, and it does not publish the composite cutoffs. These lines are reconstructed from released exams and widely-cited third-party curves, so treat them as an estimate.
- What is a good AP score?
- A 3 is considered qualified and earns credit at many colleges; 4s and 5s are strong and accepted more widely, including at selective schools.
- What changed on AP Physics 1 for 2025?
- Three things: fluids was added as a new unit (moved from Physics 2), the multi-select multiple-choice questions were removed, and the free response was standardized into four set types. The 2025 curve was also unusually generous, with the pass rate rising from 47% to 66%.
- Is AP Physics 1 calculus-based?
- No, it's algebra-based; you need algebra and basic trigonometry, not calculus. The calculus-based courses are AP Physics C: Mechanics and AP Physics C: Electricity and Magnetism.
