Barron's SAT Subject Test in Physics (widely available in various editions including the popular 2nd Edition) is a comprehensive study guide designed for the now-discontinued SAT Subject Test in Physics. While the College Board officially ended Subject Tests in 2021, these materials remain highly valued for high school physics review and AP Physics B or AP Physics 1 preparation. Core Content and Features
The guide is structured to move from foundational math skills to complex physical theories. Key features found in standard PDF versions include: Comprehensive Review Topics:
Mechanics: Vectors, kinematics (one and two dimensions), dynamics, work, energy, and power.
Electricity and Magnetism: Electric fields, potential, DC circuits, and electromagnetic induction.
Waves and Optics: Reflection, refraction, and wave behavior.
Thermodynamics and Modern Physics: Heat, kinetic theory, and atomic/nuclear physics. Assessment Tools:
Diagnostic Test: A preliminary exam with a diagnostic chart to help students identify specific weak areas before starting the full review.
Practice Exams: Usually includes three full-length practice tests with detailed answer explanations to simulate actual testing conditions. Strategic Study Aids:
"What's the Trick?": Unique sections offering shortcuts and mental models to solve common physics problems quickly.
Appendices: Quick-access references for physical constants, formulas, and a basic math review. Accessing Practice Papers
For students seeking additional practice, platforms like Collegedunia offer a vast collection of up to 44 individual SAT Physics practice papers to supplement the Barron's text.

Final verdict: Is the Barron’s SAT Physics PDF worth it?
Yes—with caveats.
- If you have a legal copy (purchased or borrowed), it is the single best drill resource for speed and endurance.
- If you download a pirated "Barron 39-S" PDF, you risk getting an outdated, virus-ridden, or incomplete file. Your time is worth more than $20.
- If you need a free resource, use the College Board’s official PDF of practice questions and supplement with HyperPhysics (online) rather than hunting for a cracked Barron’s file.
Is downloading the Barron’s SAT Physics PDF Legal?
This is a critical point. Barron’s Educational Series holds active copyrights on these materials. While you can find "free PDFs" scattered across file-sharing sites (GitHub, Archive.org, or student Google Drives), these are almost always unauthorized copies.
Legal alternatives to a free PDF:
- Your School Library: Many high school career centers have older editions you can scan chapter-by-chapter.
- Interlibrary Loan: Request the physical book via your local library.
- Barron’s E-book: You can purchase a legal e-book directly from Amazon, Google Play, or Barnes & Noble for $15–$25. This often includes interactive features.
- Used Bookstores: A used physical copy of the 10th or 11th edition costs less than $10 and contains 95% of the same relevant physics.
Warning: Downloading pirated PDFs exposes your device to malware disguised as "Barron 39-S.exe" or broken PDFs that require "password cracking software."
What is typically in the Barron’s SAT Physics Book?
The standard Barron’s SAT Subject Test Physics book (usually the 12th or 13th edition) contains:
- A diagnostic test to identify weak areas.
- Comprehensive topic reviews covering 20+ physics topics.
- Key formulas and constants reference sheets.
- Four to six full-length practice tests (two in the book, plus online access for more).
- Detailed answer explanations for every question.
The "Barron 39-S" Typo: What searchers actually find
Search engines frequently autocorrect or mis-transcribe scanned document titles. A PDF scanned in 2010 might have a footer reading "Barron’s SAT Physics - 39th Impression" or a misread font where $ looks like S. In practice, users searching for "Barron 39-S SAT Physics PDF" are looking for:
- Barron’s SAT Physics 11th Edition PDF
- Barron’s SAT Physics 12th Edition PDF
- Barron’s SAT Physics 13th Edition PDF
We will refer to the resource generically as the Barron’s SAT Physics PDF for the remainder of this guide.
Step 1: The diagnostic sprint (Day 1)
Do not read the review chapters first. Instead:
- Open the PDF and skip to the Diagnostic Test.
- Set a timer for 60 minutes (the real test is 60 minutes for 75 questions).
- Take the test cold.
- Score it. Identify your bottom three topics (e.g., Quantum Phenomena, Thermodynamics, Waves).
