Two sections, five scored components, and one detail almost every unofficial calculator gets wrong: on the redesigned exam, a raw point on the free response is worth exactly the same as a raw point on the multiple choice. What differs is how many points each question actually offers.
Discrete questions and question sets built on a stimulus — a graph, a diagram, or a short experiment description. No penalty for guessing.
Design a procedure, justify a method, or evaluate an experimental setup and its sources of error.
Move between representations — equation to graph, graph to written explanation — and connect the math to the physics. The single largest FRQ on the exam.
Multi-step quantitative problem solving. Show every line of work — partial credit is awarded per correct step, not just the final value.
The shortest FRQ, but still worth a full 8 raw points — do not leave it for the last five minutes.

The Fluids Trap: A Whole Unit Moved In, and Half the Internet Missed It
This is the single most useful thing on this page, and it is not a study tip — it is a fact about where your material is coming from. Before 2025, Fluids belonged to AP Physics 2. If any of your prep resources predate the redesign, they were never going to mention it.
Look at how the eight current units are actually weighted on the multiple-choice section:
| Unit | Weight | Pre-2025 Home | In older prep books? |
|---|---|---|---|
| Unit 2 — Force & Translational Dynamics | 18–23% | Physics 1 | Yes |
| Unit 3 — Work, Energy & Power | 18–23% | Physics 1 | Yes |
| Unit 1 — Kinematics | 10–15% | Physics 1 | Yes |
| Unit 4 — Linear Momentum | 10–15% | Physics 1 | Yes |
| Unit 5 — Torque & Rotational Dynamics | 10–15% | Physics 1 | Yes |
| Unit 8 — Fluids | 10–15% | Physics 2 | Usually not |
| Unit 6 — Energy & Momentum of Rotating Systems | 5–8% | Physics 1 | Yes |
| Unit 7 — Oscillations | 5–8% | Physics 1 | Yes |
Read the middle two columns together. Fluids now sits in the same weight band as Kinematics, Momentum, and Rotational Dynamics — worth as much as 10 to 15 percent of the exam — but it arrived from a different course. Any legacy AP Physics 1 study guide, any hand-me-down flashcard deck, any older calculator on the internet that models a “50 MCQ, 7 unit” exam is structurally unable to prepare you for a unit that did not exist in its source material.
Check your source material’s publication date before you trust it. Anything written or filmed before the 2025 cycle was built for a 50-question, 7-unit exam and will simply skip pressure, buoyancy, and continuity — not because those topics are minor, but because they weren’t there yet.
Treat Fluids like a full unit, not an appendix. Archimedes’ principle, continuity, and Bernoulli’s equation show up on both the multiple choice and, increasingly, as a scenario dressing for a Mathematical Routines FRQ. A 10–15% unit you haven’t studied costs roughly the same as being weak on Momentum.
Most students who plateau below a 4 aren’t missing conceptual ability — they’re missing a unit their materials never told them existed.
Every Point Trades Equal — But Not Every Question Offers the Same Number
AP Physics 1 has an unusually clean scoring engine. Because 40 raw MCQ points scale to 50 composite points, and all 40 raw FRQ points across the four free-response questions also scale to 50 composite points, one raw point is worth 1.25 composite points everywhere on the exam — a filled bubble on the Bluebook app and a rubric row on FRQ 3 trade at the identical rate. That is not true of most AP exams, where a written rubric row is worth several multiple-choice questions.
The leverage on this exam isn’t in the exchange rate. It’s in the ceiling: some questions simply hold more raw points than others, so a gap in a high-ceiling question costs more in absolute terms.
Fill in the five sections above and this panel will identify which one is sitting on the most unclaimed composite.
Where You Land Nationally
AP Physics 1 has one of the tougher curves among AP sciences. In the first year of the redesigned exam, 174,992 students sat it — and the results were still weighted toward the lower half of the scale, even after a major format simplification.
Official 2025 College Board distribution for AP Physics 1: 19.7% earned a 5, 24.7% a 4, 22.9% a 3, 13.4% a 2, and 19.3% a 1 — a 67.3% pass rate on a mean of 3.12, a sharp improvement over the 47% pass rate the pre-2025 exam posted the year before.
Frequently Asked Questions
Two conversions feeding one total. Your multiple-choice raw score, out of 40, is scaled to 50 composite points. Your combined free-response raw score, out of 40 across all four FRQs (10 + 12 + 10 + 8), is also scaled to 50 composite points. Add the two and you have a composite out of 100. College Board does not publish the exact cut points that turn that composite into a 1 to 5, so every public AP Physics 1 calculator, this one included, is modelling those thresholds against the official score distribution rather than reading them off a table.
Four things at once. Multiple choice dropped from 50 questions to 40, with more time per question. Free response dropped from 5 questions to 4, with a standardised set of task types and no more open-ended “paragraph argument” format. A calculator is now permitted on both sections instead of just one. And Fluids, previously exclusive to AP Physics 2, became Unit 8 of AP Physics 1. Course content otherwise stayed the same — the redesign simplified format and testing conditions rather than removing material.
Yes, and it isn’t a footnote. Fluids is Unit 8 of the current course framework, weighted at roughly 10 to 15 percent of the exam — the same weight band as Kinematics, Linear Momentum, and Torque & Rotational Dynamics. Expect Archimedes’ principle, the continuity equation, and Bernoulli’s equation to appear on the multiple choice, and don’t be surprised if a Mathematical Routines FRQ uses a fluids scenario as its setup.
None. Only correct answers count, so a blank and a wrong answer are worth the same: nothing. Answer every one of the 40 multiple-choice questions, even if it’s a guess based on eliminating two obviously wrong options. On the free response, partial credit is awarded step by step, so an incomplete but correctly set-up solution to FRQ 3 still earns points along the way.
Roughly 70 or more out of the 100-point composite modelled here, which is about 70 percent of the available points. In practice that looks like around 28 or more correct on the multiple choice alongside strong, mostly complete work across all four FRQs — particularly FRQ 2, which at 12 raw points is the single largest question on the exam and the hardest one to compensate for if it goes badly.
By pass rate, yes, though it improved substantially in 2025. AP Physics 1 posted a 67.3% pass rate and a 3.12 mean in the first year of the redesigned format — a major jump from the roughly 47% pass rate the older version posted the year before, but still on the tougher end of the AP science lineup. Part of this is genuine difficulty: the exam is deliberately conceptual rather than plug-and-chug, and it draws a broader population of students than the calculus-based Physics C exams, which tend to attract a more self-selected, already-strong cohort.
Yes, on both sections — this is one of the 2025 changes. A four-function, scientific, or graphing calculator is permitted on the multiple choice as well as the free response, along with the official equation and constants sheet, which is provided on both sections too. Being fast with your specific calculator model still matters, since raw time pressure hasn’t gone away even though the format simplified.
Generally yes, though policies vary more here than on some other AP exams. Many public universities grant credit or placement for a 3, particularly for students not majoring in a physics-dependent field. More selective institutions, and especially engineering and physics programs, often set the bar at a 4 or 5, or use the score for placement rather than credit. Check the specific policy at your target school, since AP Physics 1 credit decisions vary more by institution than most humanities AP exams.
The composite arithmetic is exact, because the 50/50 section weighting and the 40-raw-point scaling on each side are published in College Board’s exam materials. The step from composite to a 1–5 is a model, fitted to the official 2025 score distribution, because College Board has not released a public cut-score table for the redesigned exam. Expect accuracy within roughly one band near a boundary, and treat a result close to a cut point as genuinely open in either direction.
Related AP Score Calculators
AP Physics 1 sits apart from most AP exams in one respect: its two sections trade points at an identical rate. That makes its scoring engine simpler than the humanities exams, but the unit-weighting story — and the Fluids Trap in particular — makes preparation harder to get right from generic advice.

Methodology & Disclaimer
Section weights and scaling come directly from College Board’s published exam description (Reference 1) and are exact rather than estimated: 40 multiple-choice questions scaled to 50 composite points (50%), and 40 total free-response raw points across four FRQs scaled to 50 composite points (50%), summing to 100.
The band thresholds are a model, fitted to the published 2025 distribution (Reference 2). College Board releases no chart converting raw marks into a 1–5 for the redesigned exam, which means every public AP Physics 1 calculator in existence, including this one, is reverse-engineering those cut points rather than reading them off a table. Treat a result near a boundary as genuinely open.
The Fluids Trap is not an interpretation — it is read straight off the current Course and Exam Description (Reference 3), which lists Fluids as Unit 8 of AP Physics 1 at 10–15% weight, and off the pre-2025 CED, in which Fluids appeared only in AP Physics 2. The conclusion that older prep material omits it follows directly from that timeline.
