Why did we create the MCATBooster extension?

At Booster Prep, we are committed to offering innovative solutions and resources to help students better prepare for various standardized examinations. With nearly a decade of experience in the field, we are now leveraging that expertise to create something groundbreaking for students preparing for the MCAT and to help them prepare for success in medical school!

We created the MCATBooster extension to improve your AAMC® practice exam reviews with step-by-step solutions that teach you the exact logic required for test day. If you've invested in AAMC®'s official exams, you deserve clear explanations to go with them. We believe that being able to review your answers in the exam interface, see how other test-takers performed and learn from experts who scored in the top percentiles - all without leaving your study flow, is the edge you need to take your MCAT score to the next level.

You deserve to learn from the best, and our walkthroughs are created by tutors who scored in the top percentiles of the actual MCAT.  Each solution is broken down by reasoning, content, and strategy, so you understand the thinking, not just the answer. 

We provide both written and video solutions for all 7 official AAMC® MCAT® practice exams, from the Unscored Sample Test through Practice Exams 1-6, delivered in a clean, exam-style review environment with no jarring context switches, so every review session doubles as test-day prep.

After downloading the extension from the Chrome Web Store, simply open the review of your AAMC® practice exam results, and start the extension to begin reviewing your answers with our expert solutions in the official MCAT interface!

Yes! We are actively developing MCATBooster, which will include resources for the entire MCAT. All MCATBooster extension users will automatically receive an update once our full MCAT study tool is available.

In addition to our extension, our MCAT resource-building journey began with CARSBooster. It is a game-based study tool that offers specially designed games for sharpening the essential skills needed to excel in the CARS section. Whether you're a slow reader or struggle with processing lengthy CARS passages, our games are tailored to gradually enhance your abilities. CARSBooster also offers full-length CARS practice tests and passages, detailed analytics, daily CARS passages, a mobile app, and more to help you stay on top of your progress.
