Free MCAT Prep Resources: The Best No-Cost Tools, Question Banks, and Practice Tests

You don’t need to spend thousands of dollars to prepare for the MCAT. There’s a surprisingly large set of high-quality free resources — official AAMC materials, full-length practice tests, question banks, and content review — available at no cost.

This is a complete roundup. We’ve organized it by category so you can find what you actually need.

Free AAMC Materials

The AAMC is the organization that writes the MCAT, so their free materials are the most valuable starting point.

AAMC Sample Test

The AAMC offers one free full-length MCAT Sample Test in their official practice platform. It’s formatted exactly like the real exam and scored the same way. Every student should complete this as part of their prep — it’s the most authentic free practice test available.

Access it at students-residents.aamc.org.

AAMC Official Guide Questions

The AAMC Official Guide to the MCAT includes a set of practice questions covering all four sections. These are older but still representative of AAMC-style questioning. The book is sold separately, but the questions give useful signal about how AAMC phrases and tests concepts.

Khan Academy MCAT

Khan Academy has a free, comprehensive MCAT content review built in partnership with the AAMC. It covers all four sections — including hundreds of practice passages and discrete questions. This is one of the most underused free resources available.

Access it at khanacademy.org/test-prep/mcat.

Free Full-Length Practice Tests

Several major test prep companies offer free MCAT practice exams or diagnostics. These aren’t as representative as AAMC materials, but they’re useful for additional volume.

Blueprint MCAT

Blueprint offers a free half-length diagnostic exam plus a free practice bundle. The diagnostic includes a score report and section breakdown. Generally considered one of the better third-party options in terms of difficulty calibration.

Kaplan

Kaplan offers a free MCAT practice test as part of a trial. The interface is similar to the real exam, and it includes a score report with section analysis.

Princeton Review

Princeton Review offers a free full-length MCAT with detailed explanations. Difficulty may vary from the actual exam but provides useful practice.

Altius

Altius (less well-known but well-regarded) offers a free practice exam. Students who’ve used it say the difficulty is closer to the real exam than some other third-party options.

Free Question Banks

Jack Westin

Jack Westin is the go-to free CARS practice resource. New passages are released regularly, and the full archive is free. If CARS is your weak spot, this is your best no-cost option for daily practice.

Access it at jackwestin.com.

UWorld (Free Trial)

UWorld has a limited free trial that gives access to a sample of their question bank. UWorld questions are harder than the actual MCAT and are considered the gold standard for third-party question banks.

Blueprint Free Qbank

Blueprint offers a limited number of free questions through their free account tier. Worth accessing as supplemental practice.

Free Content Review

Khan Academy MCAT (Again — It’s That Good)

Worth repeating: Khan Academy’s MCAT prep section is genuinely comprehensive. It covers:

• Biology and biochemistry
• Chemistry and physics
• Behavioral and social sciences (P/S)
• CARS passages and skills

It’s especially strong for students who need to rebuild foundational knowledge in science before moving to more advanced prep materials.

Sketchy (Free Tier)

Sketchy offers limited free access to their mnemonic-based content for biochemistry, pharmacology, and microbiology. The free tier won’t get you through full prep, but it’s useful for high-yield B/B content.

Reddit r/Mcat Wiki

The r/Mcat subreddit wiki has a well-maintained list of free resources, study schedules shared by high scorers, and community-recommended tools. Genuinely useful for research.

Free MCAT Planning Tools

MCAT.tools (Free Plan)

MCAT.tools has a free trial that lets you generate a personalized MCAT study plan based on your test date and available study hours. It auto-schedules content review, practice questions, and full-length exams — and integrates AAMC resources at the right phase of prep.

For pre-health advisors: this is a tool you can recommend to students who need structure but don’t know where to start. It’s free, takes five minutes to set up, and produces a week-by-week schedule they can actually follow.

How to Combine These Resources

Free resources work best when they’re integrated into a structured plan — not used randomly. Here’s a rough framework:

Content review phase: Khan Academy + Anki decks (Milesdown, Pankow, or others)

Mid-prep practice: Jack Westin for daily CARS, Blueprint/Kaplan free FL for a baseline score

Late prep: AAMC Sample Test, then paid AAMC materials (Question Packs, Section Bank, official FLs)

Throughout: MCAT.tools to track progress and know what to do each week

A structured MCAT study plan tells you when to use each of these — so you’re not guessing.

A Note on “Free” Third-Party Resources

Some sites offer leaked or pirated AAMC materials. Avoid them. Beyond the ethical issues, the content is often outdated or formatted incorrectly, and using compromised materials doesn’t give you accurate signal about your readiness. Stick to legitimate sources.

The resources above are enough to build a serious, high-quality MCAT prep — especially when combined with a clear study plan. Start with Khan Academy and the AAMC Sample Test, use Jack Westin for daily CARS practice, and build your schedule at mcat.tools.
