Top 7 SAT Subject Test 2 Practice Tests You Must Take

Why Practice Tests Are the Only Way to Actually Prepare

Let's be real: you can read every textbook, watch every Khan Academy video, and fill notebooks with notes. But if you're not taking full-length practice tests under real conditions, you're not preparing—you're just studying.

Practice tests do what nothing else can:

For SAT Subject Test 2 exams (Math Level 2, Physics, Chemistry, Biology, etc.), practice tests aren't optional. They're the entire strategy.

The 7 Practice Tests You Should Be Taking

1. College Board Official Practice Tests

This is your starting point and your benchmark. The College Board published 2-3 official practice tests per Subject Test before discontinuing the exams in 2021.

These are the only tests that reflect the actual question style and difficulty you'll see on test day. Every other practice source is approximating this.

Where to find them:

Take these first, before you touch anything else. They establish your baseline.

2. The Princeton Review Practice Tests

Princeton Review has been making Subject Test prep books for decades. Their practice tests are generally solid, though the questions tend to be slightly easier than the real exam.

Use them for:

Don't treat your Princeton Review scores as predictions of your real performance. They're more like training wheels.

3. Barron's Practice Tests

Barron's is the other major prep book publisher, and their Subject Test tests are tough. Questions are often more complex and wordy than what College Board actually writes.

This is a feature, not a bug.

If you can score well on Barron's tests, the real exam will feel manageable. The difficulty gap might frustrate you, but it won't hurt you.

Best used after you've done at least one official practice test and know what you're up against.

4. McGraw-Hill's 5 Practice Tests

McGraw-Hill publishes Subject Test prep with five full-length practice tests per subject. That's more official-length tests than most other sources offer.

Quality is inconsistent. Some questions are excellent mirrors of the real exam; others feel off. But the volume is valuable.

Use these to:

5. Dr. Chung's Practice Tests (Math Level 2)

If you're taking Math Level 2 specifically, Dr. Chung's is worth every penny. His practice tests are known for being accurate to the real exam format and difficulty.

He includes detailed answer explanations that actually teach you the underlying concepts, not just which answer is right.

These are harder to find than mainstream publishers, but search for them. They're popular in tutoring circles for a reason.

6. REA Practice Tests

Research & Education Association publishes Subject Test prep with full-length tests and detailed review sections. Their questions are generally well-constructed and closer to College Board difficulty than Princeton Review.

What sets REA apart is their answer explanations. They're written by subject specialists who actually teach the material, not just test prep writers.

Good for: drilling specific weak areas after you've identified them from your official tests.

7. Khan Academy (Free Official Resources)

Yes, Khan Academy has Subject Test prep resources. They're free and aligned with College Board standards.

The downside: coverage is inconsistent across subjects. Math Level 2 has decent resources. Other subjects have less.

Use this to supplement paid materials, not replace them. It's great for targeted practice on concepts you're weak in.

Comparison Table: Practice Test Sources

Source Difficulty Question Quality Answer Explanations Best For
College Board Official Exact match Perfect Minimal Benchmarking, final prep
Princeton Review Easier Good Detailed Building confidence
Barron's Harder Good Detailed Advanced students
McGraw-Hill Mixed Variable Good Volume practice
Dr. Chung's (Math) Accurate Excellent Excellent Math Level 2 only
REA Close to real Very good Expert-level Deep subject review
Khan Academy Varies Good Good Free supplemental practice

How to Actually Use These Tests

Taking practice tests wrong is almost as bad as not taking them at all. Here's what works:

Step 1: Take One Official Test First

Before you study, take a full College Board practice test under timed conditions. No breaks, no phone, no stopping to look things up.

This is your baseline. It tells you where you actually stand, not where you hope you stand.

Step 2: Study Strategically

Review your results. Find your patterns:

Each pattern requires a different fix. Don't just re-read your notes. Attack the specific problem.

Step 3: Take Practice Tests on a Schedule

Once a week minimum. Every 3-4 days if you have time.

Space them out so you have time to review and study between tests. Cramming all your practice tests into one week before the exam is useless.

Step 4: Review Every Single Question

Don't just check your score and move on. Go through every question you got wrong and every question you got right but weren't sure about.

That second category is where you're losing points you don't know about yet.

Step 5: Save One Official Test for Last

Keep one College Board practice test untouched until the final week. Use it as your final mock exam to gauge your readiness.

What If You Run Out of Tests?

Realistically, you'll run through the official College Board tests faster than you'd like. Here's how to extend your practice:

The Bottom Line

You don't need all seven of these sources. You need:

That's it. Stop looking for the magic resource. The practice tests exist. Use them properly.
