AP Biology Study Guide by UWorld: Frequently Asked Questions

Yes. Every AP Biology study guide from UWorld is regularly updated to match the most recent AP Biology exam format and course framework. You can trust that all content matches current College Board standards.

The UWorld AP Biology Study Book is your complete companion for exam success. It thoroughly covers all eight official AP Biology units tested on the AP exam. The units are:

  1. Chemistry of Life – Water, macromolecules, and properties of biological molecules
  2. Cell Structure and Function – Organelles, membranes, and transport
  3. Cellular Energetics – Enzymes, photosynthesis, and cellular respiration
  4. Cell Communication and Cell Cycle – Signals, receptors, and mitosis/meiosis
  5. Heredity – Meiosis, Mendelian genetics, and gene linkage
  6. Gene Expression and Regulation – DNA replication, transcription, translation, and biotechnology
  7. Natural Selection – Evolution, Hardy-Weinberg, and population genetics
  8. Ecology – Ecosystems, energy flow, and biodiversity

This structure makes the book a complete AP Biology exam study guide, aligning with the College Board’s official AP Bio framework.

You can buy UWorld’s AP Bio prep book directly from this page or on Amazon. Both print and online versions are available, giving students flexible options to prepare for the AP Bio exam.
To maximize success, use UWorld’s AP Bio study guide to focus on key themes and exam-tested concepts. Highlight important passages, create flashcards or notes, and reinforce your learning with end-of-chapter questions. This method makes the AP Bio exam study guide an essential tool for mastering both coursework and the exam.
Yes. The online version of UWorld’s AP Bio prep book offers interactive study tools such as customizable flashcards, a digital notebook, and self-check questions.. These features make it easier for students to learn and review efficiently.
Yes. Alongside the AP Biology study book, UWorld offers a full exam prep course and free 7-day trial. These additional resources complement the AP Biology study guide and provide strategies for exam success.
UWorld does not supply a PDF of the AP Bio prep book. Instead, students gain access to our interactive online study book, which includes all the same content plus digital features like flashcards and study planner—resources you won’t find in a simple PDF.
Yes. UWorld’s AP Bio book is designed not only for AP exam preparation but also to support success in the classroom. The book provides clear explanations of topics covered in AP classes, making it an excellent resource when reviewing for midterms and finals. Students can revisit core concepts, strengthen their understanding of complex texts, and build confidence that carries through both coursework and the AP Bio exam.
A traditional AP Biology textbook is built to cover the entire course in depth and usually follows the structure of classroom instruction. UWorld’s AP Biology study guide is more focused—emphasizing the most exam-relevant material, breaks down challenging concepts into easy-to-understand sections, and provides practice checks to reinforce learning. Students rely on it to master the essentials more effectively, especially during exam preparation.
Turn to your AP Bio textbook and teacher’s lessons for full coverage and classroom discussion. Then, use UWorld’s AP Bio book to review, practice, and stay focused on exam priorities. This combined approach allows you to learn thoroughly while sharpening your test readiness. Parents can help by encouraging students to work through each book chapter alongside the matching classroom material.

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 (Qbank, Self-Assessment exam, CCS, etc.), 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 than your local time zone.

Any of our product offerings 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 logo.

You will need to register for an account in order to purchase any of our products. Once you have registered for an account or if you already have an account:

  • Verify your profile information, address, and educational status, then click the Update button
  • Enter your Billing address and credit/debit card information, then click Review Order
  • Verify that the correct product is in your cart and click Place Order
  • A purchase receipt will automatically be sent to your registered email address

If you complete your purchase but do not receive a receipt, please contact the Customer Care Team at [email protected]

You can subscribe to any of our online courses/services using a credit or debit card with a Visa, MasterCard, Discover or American Express logo. After a successful payment, your subscription will immediately be available for activation via your account on our website or available complementary mobile applications.

You can also subscribe via personal check, money order, or demand drafts taken in U.S. dollars. These types of payments should be mailed to us and should include the name of the subscription and the duration, along with the details asked for in the registration form. We will set up your account as soon as we receive your payment and notify you via email of your access credentials. All direct-mail payments must be in U.S. dollars and made payable to:

UWorld, LLC
9111 Cypress Waters Blvd
Suite 300
Dallas, TX 75019

We do not accept cash via mail, currencies other than U.S. dollars or payments via fax.

Individuals purchasing our CPA Review product 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.

All refunds are evaluated on a case-by-case basis for products purchased directly from UWorld. One case has no bearing on another. Refund amounts determined by UWorld are final.

In-App Purchases: We are unable to process any refunds for purchases made via mobile application (in-app). Please contact Apple for all refund/credit requests for Apple in-app purchases.

USMLE Step 2 CS, Step 3 CCS, Subject Reviews & Self-Assessment Exams: These subscriptions are non-refundable, non-transferable, and cannot be converted into another subscription.

CPA Review: Students may request to cancel their CPA review product only within 10-days of activation of any of the materials. To qualify for a refund, no more than 10% of the course (lectures, Qbank, or a combination there-of) may have been used per exam section. All CPA Review refunds are subject to a cancellation fee of $75 (for single section purchases) or $250 (for package
purchases), plus any applicable shipping charges. No return of merchandise is necessary.

All other Qbanks: Refunds are considered for subscriptions of more than 30 days. Refund amounts are based on the number of days elapsed since the subscription start date or the number of questions used, whichever amounts to a higher deductible.

Example scenarion: An individual purchases a 180-day Qbank subscription and generates a few test blocks equal to 20% of the questions in the Qbank. After 45 days, he/she requests a refund. Because the elapsed duration is greater than the percentage of questions used, the refund amount will be based on a subscription converted to the closest duration (60 days) by deducting the applicable 60-day subscription fee from the refund. In the same scenario, if the individual had used 85% of the questions, the refund would be 15% of the subscription fee paid.

Note 1: A processing fee of 10% (minimum of $10 and maximum of $25) will be applied to all refund amounts.

Note 2: All refunds, pro-rated or otherwise, must be requested within 360 days of original purchase. Refunds for purchases made more than 360 days ago will be issued as non-refundable, non-transferable store credit.

Note 3: Subscribers must notify UWorld of their intent to obtain a refund before activating their subscription (or) during the active duration. If the reset option is used or all of the questions are used, no refund will be allowed (see “I want to reset/delete my Qbank test history (or) start all over again, is this possible?” below for further details). No refunds will be offered for expired subscriptions.

Note 4: For combination package purchases, individual subscription fees will be applied when calculating the refund. If any self-assessment Exam(s) is utilized from a package, the entire purchase is rendered non-refundable.

Note 5: Although access to Qbanks via certain mobile devices is provided as an additional feature, it is not intended to be a replacement for computer access, and no refunds or cancellations will be honored due to user inability to install and/or use the provided software on any mobile device (regardless of whether the device meets the minimum system requirements).

Please use the following steps to purchase a renewal for your subscription:

  • Log in to your account on our website
  • Click on the User Icon in the top right corner of the screen
  • Click on the Renew button corresponding to your subscription
  • Select the Renewal duration you wish to purchase
  • Verify your profile information, address, and educational status, then click the Update button
  • Enter your Billing address and credit/debit card information, then click Review Order
  • Verify that the correct package is in your cart and click Place Order

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 or downgrade 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, unfortunately, we cannot upgrade it retroactively. If seeking to downgrade, please refer to our refund policy for available options.

We do not offer custom duration(s) or combination packages other than those outlined on the website. Please refer to our purchase page for currently available subscriptions (including discounted combination packages for some products).

Self-Assessment exam subscriptions are for 14 days each. Subscribers whose active subscription(s) have not expired can purchase renewals from 7 days or more at any time before their active subscription expires. Please refer to the respective course description page for renewal options.

We offer a demo on each of our product pages that contains a sample of the product interface and a few sample questions. We do not offer guest/trial accounts to test our software and view materials.

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.

If the user is not present, or you wish for the gift to be a surprise, please contact Support directly using the contact form to arrange payment for the gift subscription. You will need to provide the user’s registered email address so the account can be located.
