-Chancen C. Verified UWorld MCAT Online Prep User

UWorld’s MCAT preparation materials are effective because each component is designed for active, exam-level learning, setting them apart from traditional, passive MCAT prep resources.

  • Interactive “UBooks” Instead of static textbooks, UBooks are an interactive MCAT review experience. They integrate over 4,000 high-yield illustrations for visual learners, thousands of hyperlinks in the digital version and concept check questions, turning passive reading into an immersive learning experience.
  • High-Yield Videos Our short, 3-7 minute video lessons are designed to visually explain the most difficult MCAT test prep topics in a step-by-step manner. They are integrated directly with the UBooks interface to streamline learning.
  • MCAT QBank Our industry-leading QBank features over 3,000 MCAT study prep questions that mimic the exam. The true value lies in the detailed visual rationales for every answer choice.

Yes, UWorld’s MCAT prep is highly representative, as it includes all official AAMC MCAT bundle integrated directly into our Comprehensive Course.

In addition, our in-house team of MDs and PhDs meticulously crafts all UWorld-created MCAT preparation materials, from our questions to our videos to mirror the AAMC blueprint. Unlike other prep providers, our experts must pass a rigorous screening process, ensuring only the most qualified educators and physicians are creating your MCAT study resources. This ensures our MCAT practice material accurately reflects the official exam’s conceptual difficulty and critical reasoning.

“Really good, this is the most representative 3rd party material compared to official AAMC materials. Definitely recommend it, I wish I found out about UWorld sooner.”

-Christopher Y. Verified UWorld MCAT Online Prep User

UWorld offers several MCAT prep programs to fit your specific study needs. Our MCAT study programs are designed to be flexible:

  • MCAT Comprehensive Course: This is our all-in-one self-study MCAT test preparation solution. It is ideal for students who want a complete MCAT study program that includes all of our MCAT preparation materials: the 8-volume book set, 600+ high-yield videos, 3,000+ question QBank, 4,000+ flashcards, UWorld practice exam, 7 AAMC practice exams, AAMC prep hub resources and time-saving study tools.
  • MCAT Core Course: This MCAT prep package is designed for students who want our core MCAT prep materials (the books and QBank) but may have already purchased the AAMC materials separately.
  • MCAT QBank: This is our industry-leading MCAT practice material. It is the perfect MCAT review tool for students who already have prep books and the AAMC materials and want to focus on high-quality practice questions.
  • MCAT Prep Books: This 8-book set in print and digital form is an excellent MCAT study resource for students who want engaging, illustrated content review of all MCAT science and CARS subjects. Unlike other MCAT preparation program providers it includes 2 specialized CARS books.

Most students dedicate 3 to 6 months to MCAT prep, aiming for a total of 300 to 350 hours of focused review. The ideal timeline for your MCAT test preparation depends on your schedule and goals:

Targeting a Spring Test (March, April, May)

  • This is ideal. It allows you to get your score back before medical school applications open in June, making you an early applicant.
  • Standard (6-Month) Start: Begin your MCAT prep in the fall (September-November).
  • Intensive (3-Month) Start: Begin your MCAT exam prep in the winter (December-February).

Targeting a Summer Test (June, July, August)

  • This is the most popular time. You can use your summer break for a focused, full-time MCAT study program.
  • Standard (6-Month) Start: Begin your MCAT prep in the winter (January-February).
  • Intensive (3-Month) Start: Begin your MCAT prep in the spring (March-May).

Targeting a Fall Test (September)

  • This is the last possible date to test for the current application cycle. Your application will be processed later, but it is still an option.
  • Standard (6-Month) Start: Begin reviewing your MCAT prep resources in the spring (March).
  • Intensive (3-Month) Start: Begin your MCAT practice material in the early summer (June)

Targeting a Winter Test (January)

  • This is a strategic choice for students who want to apply in the next cycle. It gives you your score months before applications open, or it serves as a good date for a retake.
  • Standard (6-Month) Start: Begin your MCAT test preparation in the summer (July).
  • Intensive (3-Month) Start: Begin your MCAT review in the fall (October)

Yes, while many free MCAT prep resources are available, they often lack the expert-level explanations, accuracy, and quality control of premium MCAT preparation materials. They may be outdated or fail to reflect the real exam’s difficulty.

UWorld’s MCAT prep online bundle provides a high-value, cost-effective alternative to both inconsistent free resources and expensive, tutor-led MCAT study programs.

What sets our MCAT prep materials apart:

  1. Expert-Vetted Content: Unlike crowd-sourced or unvetted free MCAT resources, our renowned QBank, interactive books, and high-yield videos are all created by an in-house team of subject matter experts with advanced degrees.
  2. All-in-One Platform: Instead of patching together scattered resources, our platform integrates all your MCAT test preparation tools from content review to practice and performance tracking in one place.
  3. Superior Explanations: The most significant difference is our detailed rationales. We provide in-depth explanations for all answer choices (correct and incorrect), teaching you the “why” behind every concept. This level of detail in our MCAT practice material is essential for building critical reasoning skills, which free resources rarely provide.
We encourage you to see this difference firsthand. UWorld offers a 7-day free trial that provides access to our premium MCAT preparation materials, allowing you to experience our superior learning platform before you commit.

A successful MCAT prep plan requires three “must-have” MCAT prep resources:

  1. Comprehensive Content Review: You need effective MCAT preparation materials (like targeted books and high-yield videos) to master the broad range of science and CARS concepts.
  2. A High-Quality QBank: A large question bank is essential for your daily MCAT review. It builds critical reasoning skills and helps you learn from detailed explanations, making it one of the most vital MCAT study resources.
  3. AAMC Official Materials: This is a critical MCAT prep resource. As the test makers, their practice exams are essential.

UWorld MCAT study materials help students master the sciences from every angle, building a strong foundation, sharpening experimental reasoning, interpreting visual data, and solving complex problems with confidence.

  • Science Basics: AAMC-aligned lessons, videos and questions developed by subject matter experts strengthen understanding across biology, biochemistry, chemistry, physics, psychology, and sociology, building a strong foundation for true scientific reasoning.
  • Lab Techniques + Experimental Design: The Books include the UBook Lab which provides detailed descriptions and visual depictions of essential laboratory techniques in a direct, easy-to-follow way. The videos and QBank also break down complex experiments, variables, and results so students master interpreting data, identifying controls, and analyzing outcomes.
  • Step-by-Step Calculations + Reaction Mechanisms: Detailed step-by-step examples guide students through each calculation and reaction pathway, reinforcing logic, precision, and problem-solving skills essential for the MCAT.
  • Annotated Passages + Visual Data: Every passage features annotated visuals, graphs, and tables that clarify tough science concepts and train students to extract meaning from data-heavy questions.
Yes, the UWorld MCAT comprehensive review course is a fully self-paced MCAT study program, giving you complete control over your schedule. This flexible approach to MCAT test preparation allows you to study anytime, anywhere, and customize your MCAT exam review sessions to focus on your specific areas of opportunity.
UWorld provides a complete suite of MCAT prep materials designed to fit any study style. Our offerings include an all-in-one Comprehensive Course, our renowned QBank with over 3,000 expert-written questions, and high-yield digital prep books for in-depth MCAT review.

Renewal Instructions

  •   Please purchase a renewal using the "Renew" option from the My Account page
  •   To qualify for renewal pricing, course must be renewed before it expires
  •   All renewals are effective from the current expiration date and cannot be deferred
  •   Test information cannot be reset (deleted) with renewal unless eligibility criteria is met (see Help page)

Frequently Asked Questions

New Purchase: All new subscriptions go into effect from the time they are activated and not at the time of setup/purchase. A subscription can be activated immediately or any time thereafter. If your initial purchase consists of multiple courses (UBooks and Qbank), each can be activated individually and independently via your account on our website. This process of activating a subscription after purchase allows you the flexibility to start a subscription when you are truly ready to use it.

We recommend that all subscriptions be activated within 180 days of setup/purchase. Once a subscription is activated, it cannot be paused or suspended for any reason and will run continuously for the duration of the course material.

Renewal: A renewal is an extension of time to continue access to a current activated subscription. Because a renewal is an extension to an already active subscription, it is effective from the existing expiration date, not from the day of purchase and cannot be deferred to start at a later date/time.

Note: All of our subscriptions are based on the Eastern Time Zone (GMT/UTC -5 hours or New York Time), which may be different from your local time zone.

Our Prep Course can be purchased from our website with payment due in full at time of purchase via a credit or debit card with American Express/Discover/MasterCard or Visa.

Individuals purchasing our MCAT products may finance their purchase using Affirm during checkout process. Your eligibility depends on your credit score and other criteria, as per Affirm’s policies (outlined here). A soft credit check, a credit check that does not affect your credit score, will be performed by Affirm to determine your loan eligibility. You will need a US based bank account to qualify.

What is your refund policy?

All direct UWorld purchase refund requests are evaluated case-by-case. The refund amounts determined are final.

Course Purchases

Courses purchased within 1-week of activating or receiving printed material, whichever is earlier, can receive a refund. The following conditions apply:

  • No more than 10% of the course (including but not limited to Video Lectures, QBank, Flashcard Quizzes, UBooks, or a combination of any) may have been used
  • A cancellation fee of 10% (minimum $10) will apply
  • Any shipping charges will be deducted from the refund
  • Return all printed material in new condition

If your course includes printed materials, the refund will be processed only after we receive the materials and verify their condition. Please return the printed materials to the address below.

UWorld, LLC 9111 Cypress Waters Blvd, Suite 300 Coppell, TX 75019-4858

When calculating partial refunds, the retail price of each course component will be used if that component is used beyond 10% of the course. This fee will be calculated at UWorld’s discretion.

AAMC Exam

Redeemed: A $140 activation fee applies if any AAMC Exam is redeemed. Access to all purchased exams is retained through the AAMC website.

Unredeemed: If no exams are redeemed, all exams are revoked. No activation fee is applied.

AAMC Prep Hub Resources

Upon a successful transaction, you will be sent a confirmation email receipt.

A renewal is an extension of time to continue accessing an active subscription, and it will not start the subscription over, provide a reset, or grant access to additional questions that were not previously accessible. Because a renewal is an extension to an already active subscription, it is effective from the existing expiration date, not from the date of purchase, and cannot be deferred in any way to start at a later date/time.

Please note that to qualify for renewal pricing, you will need to renew the course before it expires. Renewals are not offered to expired subscriptions. If you fail to secure a renewal before the expiration date, you will need to purchase a new subscription at the regular price directly from our website to regain access to the material.

Note: All times and dates displayed for subscription expiration correspond with the Eastern Time Zone (GMT/UTC -5 hours or New York Time), which may be different than your local time zone.

Note: If your initial purchase was a combination package, you will need to renew each active subscription individually. You do not need to renew a course that has not been activated.

You may request to upgrade your subscription purchase as long as it has not been activated. If you purchase a combination package, all included subscriptions must be unused. Please be advised that current subscription pricing will apply.

If your subscription has been activated, you can upgrade within the application. Please note that the upgrade pricing within the application is different from the retail pricing.
We do not offer custom duration(s) or combination packages other than those outlined on the website. Please refer to our MCAT purchase page for currently available subscriptions.
We offer a 7-day trial of our MCAT Comprehensive Prep Course. To sign up click here.

It is possible to purchase a subscription as a gift for someone else. However, the intended recipient will need to register an account on our website (or have an account registered for them, with their profile information entered accurately). If the user is present at the time of purchase, the purchase can be made from their account on our website using any credit or debit card with a Visa, MasterCard, American Express, or Discover logo.
