Estimate your AP Physics 1 score

Our estimated lines (composite out of 100)
AP score	Best estimate	Estimated range
5	72	66–77
4	55	50–61
3	41	36–47
2	32	27–37

College Board doesn’t publish AP Physics 1 cut scores. These lines are our estimates from its 2025 score distribution and free-response averages, and each could sit about 5 points higher or lower. Practice tests also differ in difficulty from the real exam.

Count only the multiple-choice questions you got right. Wrong and blank answers cost nothing, because College Board scores that section on correct answers alone. Then mark each free-response question against its official scoring guideline, one point at a time, and give yourself a point only when your answer does exactly what the guideline asks.

The scoring guidelines for the released 2025 and 2026 questions are free on AP Central.

How the exam adds up

The exam has two sections, and each is half your score.

The AP Physics 1 exam, May 2027
Section	Questions	Time	Share of your score
I: Multiple choice	42	85 minutes	50%
II: Free response	4 (40 points)	95 minutes	50%

The May 2025 and May 2026 exams had 40 multiple-choice questions in 80 minutes and gave 100 minutes for the free response. College Board changed both for 2027. A calculator is allowed in both sections.

The four free-response questions, in exam order
Question	Type	Points	Suggested time
1	Mathematical Routines	10	20–25 minutes
2	Translation Between Representations	12	25–30 minutes
3	Experimental Design and Analysis	10	25–30 minutes
4	Qualitative/Quantitative Translation	8	15–20 minutes

College Board describes the conversion in one sentence: the free-response scores are weighted and combined with the multiple-choice result, and that raw score is converted to the 1–5 scale. It doesn’t publish the conversion itself. With each section worth half, our estimated composite out of 100 for May 2027 is:

\text{composite} = 50 \times \frac{\text{multiple-choice right}}{42} + 50 \times \frac{\text{free-response points}}{40}

For a May 2025 or May 2026 practice test, replace 42 with 40. In the 2027 model, each multiple-choice answer contributes about 1.19 composite points and each free-response point 1.25. On the 40-question exams a multiple-choice question and a free-response point are each worth 1.25 composite points, so a question you rescue in Section I counts exactly as much as a point in Section II. Our model treats all 42 presented multiple-choice questions as equally weighted and all free-response points as equally weighted. The checked official sources do not give a 2027 scored/unscored MCQ split or the operational raw-score conversion.

The estimated score lines

These are the composites we estimate a student needed for each score on the 2025 exam. They are our estimates, not College Board’s numbers.

Estimated composite (out of 100) for each AP score
AP score	Estimated line	Plausible range	Raw points out of 80	For example
5	72	66–77	58	30 MCQ right, 28 FRQ points
4	55	50–61	44	23 MCQ right, 21 FRQ points
3	41	36–47	33	17 MCQ right, 16 FRQ points
2	32	27–37	26	13 MCQ right, 13 FRQ points
1	below 32

Raw points are multiple-choice questions right plus free-response points on the 40-question exam, where each is worth the same.

In this model, a 5 takes a little under three-quarters of the raw points, and a 3 about two-fifths of them. A student who matched the 2025 average on every free-response question and got half the multiple choice right lands at 51: an estimated 3 or 4, leaning 3. In 2025, 3 was the middle score.

How we estimated the lines

College Board publishes score shares and free-response statistics. Turning those into composite lines requires assumptions about the unpublished multiple-choice results and the relationships between scores.

Where each line fell in 2025. AP scores rise with the composite, so the share of students at each score tells you where each line sat. 19.7% of students earned a 5, so the 5 line was the composite that only the top 19.7% reached. By the same count, the top 44.4% reached the 4 line, the top 67.3% the 3 line and the top 80.7% the 2 line. These figures use the global 2025 PDF (174,992 students); College Board’s historical web table lists 174,401 students and slightly different rounded shares.
How the free-response points were spread. College Board gives the 2025 average and standard deviation for each question: 4.74 of 10, 6.09 of 12, 4.93 of 10 and 4.65 of 8, with standard deviations between 2.8 and 3.7 points. Together that is about 20.4 of 40 points, or 51%.
The gap: the multiple-choice section. College Board doesn’t publish a multiple-choice average for this exam. So we sampled averages from 40% to 65% of the questions right, with a range of spreads.
Putting it together. For each set of assumptions we simulated 20,000 students from free-response score distributions fitted to College Board’s 2025 averages and spreads, added their multiple-choice scores, and read off the composite at each line’s place in the ranking. We tried 1,000 sets of assumptions and kept the 957 with a valid correlation matrix. The estimated line is the median of those runs, and the range holds their middle 80%; it is a sensitivity range for our assumptions, not a confidence interval for an official cutoff.

How far to trust the estimate

Read your result as a band rather than a verdict. These are the things that can move it:

The multiple-choice average. It’s the biggest unknown. Each 10 percentage points we add to the assumed average raises every line by about 5 composite points, which accounts for most of the plausible range.
How spread out the scores were. We also had to guess how widely multiple-choice scores varied and how closely one student’s scores on different questions went together. With the average held fixed, those guesses moved the 5 and 2 lines by up to about 3 points and the 3 and 4 lines by about 1.
Your practice test. College Board adjusts each year’s conversion so that a 3 means the same on an easier or a harder exam. A practice test that’s easier than the real one makes your composite look better than it is, and the calculator can’t tell.
Your own marking. Readers give a point only for what the scoring guideline lists, such as a derivation that starts from the right principle or an axis with both a label and a unit. Mark yourself that strictly, or your composite will run high.
The 2027 format. May 2027 has 42 multiple-choice questions in 85 minutes and 95 minutes of free response. The sections still count 50% each, and College Board says it equates scores across years and exam formats, so we use the 2025 estimates as a starting point. Equating preserves what the AP score means; it does not guarantee the same raw-score cutoff. College Board has not published a 2027 conversion.

How your free responses compare with 2025

These are College Board’s averages for the 2025 exam, the first with today’s four question types, from 174,992 students. They belong to those exact questions, so they’re a fair yardstick if you practised on the 2025 set and a rough one for any other.

Average free-response scores, May 2025
Question	The 2025 question	Points	Average	Share of the points
1. Mathematical Routines	Momentum: a block dropped onto a moving cart	10	4.74	47%
2. Translation Between Representations	Energy: a block slides down a ramp into a spring	12	6.09	51%
3. Experimental Design and Analysis	Torque: a meterstick held level by a spring scale	10	4.93	49%
4. Qualitative/Quantitative Translation	Fluids: a block in fresh water and in salt water	8	4.65	58%
All four		40	20.41	51%

Standard deviations: 2.96, 3.69, 3.11 and 2.84 points. The Chief Reader’s report gives 4.64 for question 4; the scoring statistics give 4.65.

The typical 2025 student earned about half the points on every question.

The 2025 points most students missed

The Chief Reader’s report gives the average for every single point on the 2025 free response. These are the points that fewer than a third of students earned. Half of them asked for a reason, not a calculation.

2025 free-response points earned by fewer than a third of students
Point	Earned it	What it asked for
Q1 B2	10%	When the new block slides on the cart, say why the system’s momentum stays constant: the friction between block and cart is internal to the system, so the net external force is still zero.
Q2 B4	17%	A correct expression for the spring constant. The report names two places derivations went wrong: getting the drop in height from the distance along the ramp, and squaring (4D) as 4D² instead of 16D².
Q3 B2	20%	Say exactly how the slope of your graph gives the block’s mass.
Q1 B3	22%	Back the same claim with equal and opposite changes in momentum (or impulses) for block and cart, or with the link between the system’s momentum and the net external force.
Q2 D2	22%	Justify the change in speed with both the gravitational and the spring potential energy, not just one of them.
Q3 D1 and D2	28% each	Relate the slope of the best-fit line to the meterstick’s mass, then get a value between 0.90 and 1.15 kg.
Q4 A2	32%	Say that the block has the same weight in both liquids, so only the buoyant force differs.

“Earned it” is College Board’s mean score for that one-point part.

The FRQ guide takes each question type apart, and the experimental design guide goes through question 3 point by point.

Why older calculators and pass rates mislead

From 2015 to 2024, fewer than half of AP Physics 1 students scored 3 or higher in every year but 2020. In 2025 the figure was 67.3%, and in 2026 about 68%. 2025 brought the first exam of the revised course, and it was the year College Board set new score standards for Physics 1, drawing on 205 college professors and the grades of 43,323 of their students.

Lines drawn to match the old pass rates would sit well above the 2025 ones and would tell you that you need more points than you do. The score distribution page has every year’s numbers and College Board’s account of what changed.

Where to get scores to enter

Free response: the 2025 and 2026 questions, free on AP Central. They’re the only released sets in the current four-question format, and the 2025 set also comes with real student responses and the readers’ commentary.
Older free-response sets: AP Central still posts the 2024 questions, but College Board notes they don’t completely align with the current exam. They were written for a five-question exam, so their points won’t fit this calculator.
Multiple choice: recent multiple-choice sections aren’t released. Teachers can assign secure practice questions in AP Classroom.
