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.

We are very grateful to our men and women in uniform for their service to our country!

If you are an active duty member of the US armed services, we offer a 10% discount on the purchase of any of our new packages.

If you would like to take advantage of this offer, please submit a copy of your SCRA Status Report from the DMDC (as well as the product/package you wish to purchase) to [email protected] so that we may arrange a discount code for you. (please do not send a copy of your CAC, other military ID, or orders, as this is a violation of both military regulation and federal law)

Please be aware that the Military Discount is applicable to new package purchases ONLY. Renewal purchases are not eligible, and it cannot be retroactively applied to past purchases.

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

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 $200 (for package purchases), plus any applicable shipping charges.  No return of merchandise is necessary.

All other Qbanks:  No refunds are allowed for the first 30 days of any subscription unless the subscription has not been activated.  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 scenario:  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.

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.

The personal information that a subscriber provides is highly secure and the credit/debit card information will not be stored after the transaction is processed.  All subscription payment information is sent over a 256-bit encrypted SSL connection to the payment gateway.

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.

A subscription goes into effect from the time it is activated and not from the time of setup/purchase.  It can be activated from our website immediately or any time thereafter without any set deadline for activation.

Self-Assessments:  These subscriptions, even those purchased together, are activated (and subsequently expire) independently from one another and from any other subscriptions they may have been purchased with.  No Self-Assessment will expire (or otherwise become unavailable) until it has been activated and runs through its full duration, regardless of the status of any other subscription in your account.

CPA Review:  All sections/subscriptions included in this package are activated concurrently and, subsequently, expire concurrently.

To activate and/or access a subscription:

• Log in with your login credentials.
• Click on the Activate button associated with the course you prefer to activate.
• Click on the Launch button for the course you want to access (you may need to refresh the page in order to see the launch button).

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.

This could happen for two reasons:

• Multiple accounts in our system:  You may have created multiple accounts on our system and are most likely using a different account.  Please email [email protected] with pertinent details of your transaction (last 4 digits of the card number, amount charged, date of transaction, and billing address) so that we can look up your specific transaction to locate your correct account.

• Expired subscriptions:  All of our subscriptions are based according to the Eastern Time Zone (GMT/UTC -5 hours or New York Time), which may be different than your local time zone.  Some users may assume that the date and time associated with their subscription reflects their current local time zone, when, in fact, it does not.

• Wrong mobile app downloaded!:  We maintain different mobile apps for each of our different product types. (i.e. USMLE, Boards, NCLEX, MCAT, College Prep, etc.) Please make sure that you have downloaded the correct app for your subscription.

If you have forgotten your password, please enter your email address in the field under Forgot Password? to reset your password.  You may be required to answer a security question correctly in order to set a new password without the password reset link.  This security question will be one of the two questions you chose when registering your account.

Please note that you must specify your registered email address in the Forgot Password? retrieval dialog box as we do not send these instructions to alternate email addresses.  Some mail servers may flag the automatic password retrieval message as spam; therefore we recommend that you check your spam/junk mail folder as well.

If you are unable to locate the log-in retrieval email (or no longer have access to the originally registered email address), please contact [email protected] for further assistance.

It is critical that you keep this information updated as all communications related to your subscription rely on the accuracy of your profile details.

The username in our system is the same as your email address.  The updated email address will become your new username.

You may update your registered email address by doing the following:

• Sign in to our website using your existing username and password combination.
• Click on the Profile tab.
• Enter your desired email address in the Email field under User Information.
• Check availability and click Update if available to save changes.

To update your password, fill in the required fields under the Change Password section.

• Enter the current or temporary password.
• Enter a new password (minimum of 8 characters).
• Re-enter the new password to confirm.
• Click Update to save changes.

CPA Review:  No resets are available for the CPA Review.

All Other Qbanks:  We offer a one-time reset option with subscriptions that have been active continuously for 180 days or more.  Once a reset has been used, a subscription cannot be reset again, regardless of the duration remaining on the subscription or purchase of additional renewals.

If you want to redo certain questions and ensure that you do not have duplicate questions in subsequently generated test blocks, we recommend that you use the 'Marked' question mode.

Once a test is generated via the 'Marked' question mode, all questions within that test are no longer marked.  Therefore, you could work through the Qbank or select individual subjects a second time according to your preference.

To mark a question, click the checkbox beside the red flag icon during testing or review (on mobile devices, tap the red flag icon to mark the question).  Once you have your questions marked, you can then generate new tests using the 'Marked' question mode.

If you would like to generate the same questions in a new test a third/fourth/etc. time, you will need to 'mark' these questions again (as each time a test is generated via the 'marked' option, the questions are removed from the 'marked' pool).

Printing, saving, copying, screen capture, etc. of UWorld Qbank materials is strictly prohibited. Attempts to use system commands or third-party utilities to capture/print/save/copy our content is considered copyright infringement and breach of Terms and Conditions.  We monitor all user activity diligently, and repeated attempts to circumvent this may lead to account suspension, termination without refund, and/or legal action.  All of our subscriptions are available for online use only.  Any print copies or offline copies of UWorld products are unauthorized reproductions and are considered illegal.

Certain sections of your subscription can be printed for your records.  These pages will be indicated with a Print option or printer icon.

Qbank & Self-Assessment exam subscriptions:  Notes may be printed from the Notes tab.  Analysis may be printed per test.  Cumulative performance/score report may be printed from the Performance section.

STEP2 CS, STEP3 CCS:  Sample patient notes from the STEP2 CS may be printed.  Some reference pages that include a Print icon may be printed.  STEP3 CCS Read-out (non-interactive) cases may be printed.

No other section of any subscription is available for print/save.

When connecting using different internet access points, or at times during regular use of the Qbank, the Java cache (which stores temporary files associated with UWorld's desktop clients) may become corrupted, which can prevent your subscription from launching properly.  The following instructions will clear the temporary files from the Java cache and will usually resolve most "Unable to Launch" errors.  This will not affect your subscription data, as it is stored securely on our remote servers.

If the issue persists, please contact [email protected] with a screenshot of the Exception tab found when clicking Details on the error message. This will allow our support representatives to determine the cause of the error and provide further instruction.

There are few possible reasons for this issue:

• Personal firewall: There may be a firewall on your computer and/or network that is preventing download of necessary components.  You may need to completely turn off any internet security or firewall software on your computer, as many common security software programs (AVG, Norton, McAfee, ZoneAlarm, etc.) block such access by default.
• Connection-related issue: Your internet connection may be down, or you may be connecting on an unreliable internet connection.  If you are using a wireless connection, try repositioning your device to get the best signal possible.  If you are connecting via a wireless network with many users, it's possible that there may be insufficient bandwidth for your device to receive a response from our servers in a timely manner.  In this case, we recommend that you access the internet from a dedicated home/personal infrastructure-based internet network (DSL, cable, etc.)
• DNS maintenance/outage: Your internet service provider (ISP) performs a DNS lookup function each time you access a name on the internet (for example, turns an internet name like www.uworld.com into an internet address, such as 72.32.48.106).  Sometimes you can experience problems with your ISP connection, including conversion of the website name to an IP name and performing a time-consuming lookup.  You will have to raise this issue with your provider.  This issue usually resolves in 3-5 hours depending on the DNS cache your ISP is refreshing or rechecking.

As an alternative, we suggest using a third-party DNS server such as the OpenDNS service to avoid future problems.  You can find instructions and setup help for using OpenDNS on https://www.opendns.com/start/computer (this is a free service and does not require registration).

You can also try to access our services from an alternate internet access point while your ISP works on addressing the DNS lookup issue.

This error usually occurs when the date and time on your system do not match the location of your current internet access point.  For security reasons, your system will attempt to validate the security certificate for our application before it launches.  If the system date and time do not match the expected value, your system will not launch the application.

For Windows systems:

• In the bottom right-hand corner of your screen, check the time and date on your system.
• If the system time and date are incorrect, click on the date and then click Change time and date settings... which will open a new window, Date and Time.
• Click on Change time zone... to select your current time zone from the drop-down menu. If you are located in a region where Daylight Savings Time applies, check the checkbox beside "Automatically adjust clock for Daylight Saving Time." Click OK.
• If your system time and date are still not correct, click on Change date and time…, which will open a new window, Date and Time Settings.  Manually select the correct date and time for your current time zone and click OK.
• Click Apply to finalize the changes and click OK.
• Restart your computer. After your computer has restarted, open the application again.

For Mac systems:

• In the top right-hand corner of your screen, check the check the time and date on your system.
• Click on the time and select Open Date & Time Preferences, which will open a new window, Date & Time.
• Click on the padlock icon and enter your system password to enable changes.
• Click on the Time Zone tab and check the checkbox beside "Set time zone automatically using current location."
• If you receive a prompt that states "Location Services are turned off," click on Open Privacy Preferences... to open a new window, Security & Privacy.  Then, click the padlock icon, enter your system password to enable changes, and check the checkbox beside Enable Location Services.
• If you do not wish to enable location services, use the map to select your current time zone.
• Close the Date & Time window and restart your system. After your computer has restarted, open the application again.

If the error persists after attempting the above instructions, you may need to clear your Java cache. Please refer to the Resolving "Unable to launch the application" error section for instructions on how to clear the Java cache.

If your subscription freezes during log-in or will not proceed past the "Authenticating User" stage, this typically means that the client is unable to establish a sustained connection to our servers.  There are a few possible reasons for this error:

• Personal firewall: There may be a firewall on your computer and/or network that is preventing download of necessary components.  You may need to completely turn off any internet security or firewall software on your computer, as many common security software (AVG, Norton, McAfee, ZoneAlarm, etc.) block such access by default.
• Web accelerator: A web accelerator is active on your local machine (installed automatically as part of your Internet Service Provider or manually installed).  Disable the program(s) and try to access the our software once again.
• Network issue: If you are connecting via a public network (work, hospital, library, public Wi-Fi, etc.), please be advised that most public network administrators rely on firewall and/or proxy servers to manage internet access on their network, which may be blocking access.  In this instance, you will need to request that the network administrator make an exception to https://www.uworld.com by Java Web Start.  If they are unable to make an exception, you will need to use your subscription from a non-public or home network.

If the issue persists after disabling security programs/web accelerators, and you have tried a different network, you may need to clear your Java cache. Please refer to the Resolving "Unable to launch the application" error section for instructions on how to clear the Java cache.

This is typically caused when Java settings on your computer have either been updated manually or automatically.

• Repeat these steps for the .jar file also.
• Close the Set Associations window.
• Sign in to your account and follow the appropriate link to launch the software.

This problem might arise if you lose your internet connection while course content is being downloaded onto your computer.  The test is downloaded on your machine while the images and media are stored on the server.  Therefore, you may be able to move from one question to the next in absence of internet connection, but the images and media will not load.  This is especially true if you are using a wireless (3G/GPRS/GSM/UMTS/CDMA/HSDPA/WiMAX/Wi-Fi) or dial-up connection.

If you rely on dial-up access, we recommend trying to access the course from a high-speed internet access point if possible. If you rely on wireless access, please disable the wireless device on your computer and try using a wired connection from your computer to your internet access point to avoid this issue. If the problem exists on a wired connection, then email us your username, contact number, and a suitable time to reach you by telephone. We will check if the connection is working properly.

Our qbank requires reliable and stable connection in order to download images and save tests while communicating with our servers. Wireless connections are great in terms of offering flexibility with connection but are quite unreliable when providing sustained and reliable internet connectivity.

If you are accessing our software from a computer for which you do not have sufficient rights (public terminal at hospital, library, etc.), you may need to seek assistance from the computer administrator or use it from a computer on which you have full administrative rights. 

If you continue to receive this error after ending the process, this means that the conflicting program may be set to launch automatically or run in the background.  In this case, you will need to locate the program in question, open it, and modify its settings so that it does not launch automatically or run in the background.

If you receive this error message, or if your Qbank shows visual glitches when you are scrolling through your test (such as text repeating multiple times or the interface appearing to "freeze"), please use the following troubleshooting steps to uninstall Java and the Qbank and then reinstall from scratch:

• Delete all UWorld icons from your desktop, quick launch bar, and Applications folder (if they exist).
• Click on the Apple logo and select System Preferences from the menu, then click on Security & Privacy.
• Under the General tab, change the settings for "Allow applications downloaded from" to "Anywhere". You may need to click the padlock icon and enter your system password to unlock this section for editing.
• Refer to the How do I install The UWorld USMLE Client on Mac (OS X 10.9.0 or higher)? section of the help page.
• Carefully follow the provided instructions to be sure that the Apple patch as well as the latest Java update is completely installed before launching the Qbank.

If you are still unable to launch your subscription after proceeding with the provided steps, please contact us directly at [email protected] and include a screenshot of the error message you receive when attempting to launch.
