📊 Unit Confidence Tracker — 8 Units
Rate your confidence in each of the 8 units. Unit 8 (Fluids) is new — moved from AP Physics 2 starting 2025.
🆕 What Changed in 2025 (and Stays for 2026)
AP Physics 1 underwent major revisions starting May 2025. The result? Pass rate jumped from 47.3% to 67.3% — the biggest single-year improvement of any AP exam. Here's what changed:
| Feature | Old Format (pre-2025) | New Format (2025+) |
|---|---|---|
| MCQ Count | 50 questions | 40 questions |
| MCQ Choices | 5 choices + multiselect | 4 choices only |
| MCQ Time | 90 minutes | 80 minutes |
| FRQ Count | 5 questions | 4 questions |
| FRQ Time | 90 minutes | 100 minutes |
| Calculator | NOT allowed | YES — allowed! |
| Units | 7 units | 8 units (Fluids added) |
| Pass Rate | ~45% (2024) | 67.3% (2025) |
| Mean Score | 2.59 (2024) | 3.12 (2025) |
How AP Physics 1 Scoring Works
The exam has two equally weighted sections. An equation sheet with formulas and constants is provided for both. Calculators (4-function, scientific, or graphing) are allowed on both sections — a major change from pre-2025.
| Section | Questions | Time | Weight | Raw → Scaled |
|---|---|---|---|---|
| I: Multiple Choice | 40 Qs (4 choices) | 80 min | 50% | 40 → 50 pts |
| II-Q1: Mathematical Routines | ~25 min | 100 min | 50% | 10 pts |
| II-Q2: Translation (TBR) | ~25 min | 12 pts | ||
| II-Q3: Experimental Design (LAB) | ~25 min | 10 pts | ||
| II-Q4: Short Answer / Paragraph | ~25 min | 8 pts |
Composite = (MCQ correct / 40) × 50 + (FRQ raw / 40) × 50 = out of 100.
Unit Weights on the AP Physics 1 Exam
The exam now covers 8 units. Energy (Unit 4) is the heaviest at 20-28%. Fluids (Unit 8) is new — moved from AP Physics 2 starting 2025.
Key Equations Reference
An equation sheet is provided on the exam. Here are the most frequently tested equations across the 8 units.
2025 AP Physics 1 Score Distributions
In 2025 (first year of the revised format), 174,401 students took the exam. The pass rate surged to 67.3% — up from 47.3% in 2024, the biggest single-year jump in AP Physics 1 history.

Exam Strategies by Section
Multiple Choice
Now only 4 choices — easier to eliminate. Draw free-body diagrams for forces problems. Use dimensional analysis. Calculator allowed but most problems are conceptual. Budget ~2 min per question. No penalty for guessing.
Q1: Mathematical Routines
Show ALL derivation steps. Start with a fundamental principle (conservation law). Define variables clearly. Use symbolic math — plug in numbers only at the end. Label final answers. Common topics: momentum, energy, kinematics.
Q2: Translation (TBR)
Practice energy bar charts, graphs, and diagrams. Translate between words → equations → graphs. Conservation of energy is a frequent topic. Label graph axes with units. Be consistent between different representations.
Q3: Experimental Design
Name specific equipment. Describe step-by-step procedure. Identify independent/dependent variables. Explain how to reduce uncertainty (repeat trials). Plot linear graph — relate slope to unknown. This is often the most points-rich FRQ.
AP Physics 1 vs Physics C: Mechanics
| Feature | AP Physics 1 | AP Physics C: Mechanics |
|---|---|---|
| Math Level | Algebra-based | Calculus-based |
| Topics | Broad mechanics + fluids (8 units) | Deep mechanics (fewer units) |
| Calculator | Yes (since 2025) | Yes |
| MCQ | 40 Qs, 80 min, 4 choices | 40 Qs, 80 min, 4 choices |
| FRQ | 4 Qs, 100 min | 4 Qs, 100 min |
| 2025 Pass Rate | 67.3% | 73.3% |
| 2025 Mean | 3.12 | 3.35 |
| Best For | Non-calculus students, pre-med | Engineering, physics majors |
