Best Free MCAT Resources in 2026: Practice Questions, Full-Lengths and Apps

The best free MCAT resources in 2026 are the AAMC's free official materials (Practice Exam 1, the Unscored Sample Test and the content outline question course), Khan Academy's MCAT videos, and Anki, paired with Oncourse AI, an adaptive MCAT question bank and AI tutor that turns your wrong answers into targeted daily review. Start with the official AAMC tools, add one free content source, and use Oncourse AI as the practice and review layer that keeps weak topics coming back until they stick.

Free MCAT prep can carry you a long way. The AAMC now gives every student two free full-length exams, and several commercial companies offer a free full-length or diagnostic. The problem is rarely a lack of material. It is too many tabs and no system for reviewing mistakes.

1. Oncourse AI: Best Free MCAT Prep Layer for Practice and Review

Oncourse AI is the top pick because free MCAT resources only work when mistakes get reviewed and revisited. It combines an AI tutor, adaptive question practice, flashcards with spaced repetition, previous-paper-style practice and weak-area review in one place.

Use it every day between full-lengths. When you miss an amino acid question, an equilibrium calculation or a CARS reasoning item, Oncourse AI brings that topic back in a short session instead of leaving it in a spreadsheet you never open. The AI tutor can explain why the right answer is right and why your choice was wrong, which is the step most free question sources skip.

It pairs well with the AAMC materials: use official exams to measure, and Oncourse AI to repair. See our full MCAT prep app ranking for how it compares with paid tools.

2. AAMC MCAT Official Prep: Best Free MCAT Full Lengths

The AAMC is the test maker, so its free materials matter most. You currently get:

• Practice Exam 1 (free, scored): 230 questions from previously administered exams with a scaled score and percentile.
• Unscored Sample Test (free): 230 questions with full exam functionality but no scaled score.
• What's on the MCAT Exam content outline course: free practice questions mapped to the content outline.

Find them on the AAMC free planning and study resources page. Save Practice Exam 1 for when your content base is solid so the score means something.

3. Khan Academy: Best Free MCAT Study Resources for Content

Khan Academy's MCAT collection, built with the AAMC, covers biology, biochemistry, chemistry, physics, psychology and sociology through videos and passage practice. It is strongest for psychology and sociology, a section many students underprepare.

Do not binge it. Watch one topic, then test that topic the same day.

4. Anki: Best Free MCAT App for Flashcards

Anki is free on desktop and Android and is the most common free MCAT flashcard tool. Community decks cover amino acids, hormones, equations and psych/soc terms.

The risk is overload. Cap new cards per day and suspend cards you already know cold.

5. Free Full Lengths from Commercial Companies

Blueprint, Kaplan and Princeton Review each advertise a free MCAT full-length or diagnostic in exchange for an account. They are useful for stamina and timing. Treat their scores as rough estimates, since only AAMC exams use official scoring.

6. Reddit and Student Doctor Network Resource Lists

r/Mcat and Student Doctor Network keep community lists of free MCAT resources, CARS passages and study schedules. They are good for discovery, but check that each link is still current before you build a plan on it.

Best Free MCAT Apps for Studying on Your Phone

For short sessions, the best free MCAT apps are Oncourse AI for adaptive questions and review, AnkiDroid (free on Android) for flashcards, and the Khan Academy app for videos. Use your phone for recall and question practice, and save full-lengths for a desktop under timed conditions.

How to Build a Free MCAT Study Plan

1. Take the AAMC Unscored Sample Test early as a baseline if your exam is 3 or more months away.
2. Review content with Khan Academy, one topic at a time.
3. Do daily questions and weak-area review in Oncourse AI.
4. Keep Anki small and daily.
5. Add one commercial free full-length mid-prep for stamina.
6. Use AAMC Practice Exam 1 in the final phase.

If cost is a barrier, check the AAMC Fee Assistance Program before buying anything. Approved students get official prep products included.
