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

Step 2 CS, Step 3 CCS, Self-Assessment Exam (SimExam) and Subject Review: These subscriptions are non-refundable, non-transferable, and cannot be converted into another subscription.

Step 1, Step 2 CK, and Step 3 Qbank: No refunds are allowed for the first 30-day duration of any subscription, unless the subscription has not been activated. Refunds are considered for subscriptions with more than 30-day duration. Refund amounts are based on the number of days elapsed since the subscription start date or the amount 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 request for a refund. As 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 applicable 60-days subscription fee from the refund. Additionally, 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 $10 transaction processing fee applies on all refund amounts.

Note 2: The subscriber must notify USMLEWorld of their intent of 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).

Note 3: For combo package purchases, individual subscription fee will be applied when calculating the refund.

Note 4: While access 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 a user's inability to install and/or use the provided software on any mobile device (regardless of whether or not the device meets the minimum system requirements).

You will encounter this message when the IP address that is currently assigned to your computer by your internet service provider has been blocked. There might have been fraudulent transactions from a similar IP or an IP within a close range in the past. This does not imply that you have made any fraudulent transactions. It is just a security measure that we have adopted to avoid fraud on our website

In order to properly subscribe, you will need to fax your information to 972-887-3296:

• your full name, address, phone #, email address, and username (if you created an account on our website)
• course name(s) and duration you prefer to subscribe
• payment information (credit card number, billing address, CVV code, expiration date, etc)

Once we receive the requested information we will process it and notify you at the email address your specified with your account details. Upon subscription, access to your course material will not be blocked even though you received a "Blocked IP Address" message initially. Your submitted details will be held in strict confidentiality and will only be used to setup the subscription. Due to insecure nature of email communication, do not submit payment details (card number, expiration date, security code) via email.

Unfortunately, we do not offer discounts to individual subscribers for purchase of a new subscription based on affiliation(s). We offer group discounts on Step 1 and Step 2 qbank products with subscription duration lasting 3/6/12 months only with a minimum purchase of 50 subscriptions by individuals from the same school/program. To inquire more about group discounts, please contact us with all of the details below.

• Number of users in group (guaranteed enrollments)
• Desired USMLE Step (Step 1 or Step 2)
• Desired subscription package(s) from those outlined on https://www.usmleworld.com/purchase.aspx page for Step 1 or Step 2
• Payment responsibility (Group Coordinator/ School / Individual group member)
• Group coordinator Name, Email address, Tele #

Card declined/General Transaction Failure: When you encounter this message during the subscription process, it means that your subscription payment transaction did not go through. Your card-issuing bank has declined the transaction as it may not match your online transaction pattern, it exceeds your purchase limit, or there was an incorrect entry of subscriber information, including card number, card code, expiration date, name on card, etc. Please contact the card-issuing bank to resolve the problem and then try the operation again. If you prefer, you can also use a different card or payment means as mentioned above. Your account is still created when a payment has been declined/rejected but the subscription will be added only after a successful transaction has been made. Click Register and log-in with the username & password then subscribe to your desired course.

Incorrect CVV2 Code: When any code mismatch occurs, you will encounter this message. Because this is a security-related issue, you will not be charged for this transaction even though your card-issuing bank may approve authorization. Please enter the correct card code (CVV2 number), credit card number, and expiration date. The card code or Card Validation Code (CVC) or Card Verification Value 2 Code (CVV2) is the three-digit code located next on the back signature strip of Visa, MasterCard and the four digit code located on the front of all American Express cards (see an example here for more information and then try the operation again).

The personal information that a subscriber provides is always highly secure and we do not store any credit card information. When purchasing a subscription, all such payment information is sent over 128-bit encrypted SSL connection to payment gateway. Your credit card payments will be processed using the AuthorizeNet Payment gateway. AuthorizeNet, is the preferred global payment-processing service for e-commerce, providing server-based, multi-currency payment solutions. Thus, this will enable customers to process secure transactions in real time, 24/7, and use multiple currencies.

New Purchase: All subscriptions go into effect from the time they are activated and not the time of setup/purchase. It can be activated immediately or anytime thereafter. If your initial purchase consists of multiple courses (qbank, self-assessment exam, CCS, etc.), you must activate each of them individually via your account on our website as preferred. This process of activating a subscription after purchase allows you flexibility of starting a subscription when you are truly ready to utilize it.

Our self-assessment exam subscription is independent of other subscription duration. It can be activated via your account on our website and will stay active for 2-weeks from the time of activation. You can activate it before, during or after your other subscribed course material.

We recommend that all subscription 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 said course material.

Renewal: A renewal is basically an extension of time to continue access to an active subscription. Since 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 according to the Eastern Time Zone (GMT/UTC -5 hours or New York Time), which may be different than your local time zone.

A renewal is basically an extension of time to continue access to an active subscription. Since 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.

All renewals are effective from the existing expiration time, NOT from the time of purchase and cannot be deferred to start at a later time. To qualify for renewal, you will need to renew the course before it expires. Renewals are not offered for expired subscriptions, and you will have to purchase a new subscription at regular price for minimum of 30-days.

Please log into your account via http://www.usmleworld.com and click on "Renew" button. This option provides a list of available "renewal durations and their prices" for the selected course. You can select and renew your existing course for a desired duration of time.

Note: 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.

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.

Once activated, all subscriptions run continuously for the subscribed duration without any intermediate breaks. Subscriptions cannot be suspended temporarily and/or reactivated at a later time.

You are allowed to access your account and use your subscription(s) 24/7, regardless of your location as long as the device/network being utilized meets the system requirements as outlined here. However, there are certain regulations that apply. The registered subscriber is the only individual who is allowed to access their account and subscription(s), and access can only occur on ONE device at any given time (e.g. You can use your subscription from 9AM - 5PM from your work location and resume 6PM - 11PM at home, but there cannot be any overlap). All log-ins are diligently monitored and if a single account has been used from multiple devices at the same time, it will be immediately terminated without any explanation or refund.

The minimum duration of a new subscription purchase (qbank(s), Step 2 CS or Step 3 CCS) is 30-days and are not available in any other shorter or custom durations. Subscribers whose active subscription(s) have not expired can purchase renewals for before their active subscription expires. Please refer to the respective course description page for renewal options.

Note: 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.

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 an incorrect account. Please check the latest receipt of your subscription purchase for the username and password associated with your latest subscription and try again
• 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 the date and time associated with their subscription reflects their current local time zone, when in fact, it does not

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

• Please log into your account via http://www.usmleworld.com
• Click on "Change Profile" or "Change Password" link on the left hand-side navigation pane

Note: For security reasons, we do not discuss account/subscription related concerns via a non-registered email address (basically the email address being used to communicate with us MUST match the one in profile details).

Please keep in mind that reset eligibility is based on the concurrent duration of your currently active subscription and does not take into account previous subscription(s). A reset is basically a permanent and irreversible purge (delete) of all of your test and performance data from our system. This option is available in only two scenarios outlined below:

• Purchase of a new subscription: You purchased a brand new subscription (i.e. your previous subscription has expired and you did not renew) and still have the old information in your Qbank
• Continuous subscription for 6-months or more without a reset: For users who have continuously subscribed to a particular course for 6 months or more and whose subscription has never been reset, we provide a one-time only opportunity to reset your test information/Qbank
  • If you purchased a 180-day or more subscription outright (6 months or greater duration when you purchased your active subscription) you can perform a reset yourself by accessing "Utilities" -> "Reset" section of your Java based qbank interface
  • If you have held your active subscription continuously for 6 or more months without any intermediate breaks and it has not been reset previously, please email us your reset request including your username so we can make the reset option available via the Java based qbank interface

Renewal of an active subscription does NOT qualify as a new subscription. Qbank test information cannot be deleted or reset in the middle of a subscription except in above two scenarios.

• Step 1 Qbank, Step 2 CK Qbank, Step 3 MCQ or self-assessment exam: We do not offer guest/trial accounts to test our software. However, you can view a non-interactive demo of our software from each of the product pages. You will need to have Adobe Flash Player installed on your system to view the demo.
• Step 2 CS or Step 3 CCS:
  Step 2 CS demo is available at: http://www.usmleworld.com/Step2CS/step2cs_demo.aspx
  Step 3 CCS demo is available at: http://www.usmleworld.com/Step3/Step3_CCS_demo.aspx

All of our products have a finite set of questions/cases and we routinely review and update them based on new research, changes in diagnostic and patient management practices. Question containing older or non-relevant material are replaced with updated question content.

• Questions for Step 1 do not change that often as they are based on core scientific principals
• Questions for Step 2 are added and/or changed based on new diagnostic procedure and medical research (this occurs quite frequently)
• Questions for Step 3 are changed also based on new protocols in patient management (not as frequently as Step 2)
• Questions in our Self-assessment exams, Subject Review are changed only if the question/concept is obsolete
• Step 2 CS and Step 3 CCS cases are updated based on new protocols in patient handling/management

Once a new question/case is added or an existing question/case is updated, it is automatically made available to all users with an active subscription to that particular course (regardless of their course subscription duration).

Once a test is generated, it cannot be deleted from your account or adjustment made to the used/unused/incorrect/marked question pool. Please use "Resume" option associated with the test in question from "Previous Test" section to suspend it or complete it so as to prevent it from adversely affecting your cumulative performance metrics.

If you are accessing our Step 3 MCQ via a web browser based interface contact us with your username and the test ID number(s) that you would like suspended.

It is highly recommended that you use and review the documentation provided with Primum Computer-Based Case Simulations offered freely by USMLE on their "Practice Materials" page located at http://www.usmle.org/practice-materials/index.html prior to subscribing or using our Step 3 CCS interactive software. As part of the freely available material by USMLE, you will learn how to efficiently use the interface, write orders, advance the clock and perform basic patient management tasks via a very detailed presentation.

Our offering assumes that you have used Primum Computer-Based Case Simulations offered by USMLE prior to using our interactive software.

This is typically caused when your Anti-Virus, Anti-Spyware, or cache management software removes portions of the Java cache necessary for our program to properly function. It can also occur when users frequently change their internet connection provider (Work, Library, Personal, Public Wi-Fi etc.), or if the software does not properly update (which should occur automatically without prompting).

If you find yourself switching internet access point on a frequent basis, always launch your web browser to verify you have direct internet access before launching our course material via desktop shortcut to avoid future cache corruption. If connecting via Wi-Fi, we also recommend that you make sure that your computer always has the best signal possible.

• Click here if exception is "Java.net.SocketException:" (Software caused connection abort / Network is unreachable / No route to host / Connection timed out / Operation timed out / Connection Refused)

  This indicates that your internet connection may be down, or you may be connecting on an unreliable internet connection. If you are using a wireless connection, we recommend that you try repositioning your computer to get the best signal possible. If you are still having difficulty, we recommend that you try connecting via a wired connection to see if it may be a problem with your wireless access point.

  Additionally, if you are connecting via a wireless network with many users, it's possible that there may be insufficient bandwidth for your computer to receive a response from our servers in a timely manner. In this instance, we recommend that you try connecting via a home/private internet network.

  It's also possible that your internet service provider (ISP) may be performing maintenance on their DNS server. In such, a DNS server turns an internet name like http://www.usmleworld.com into an internet address like http://72.32.48.106. If your computer is not able to communicate with the DNS, or the DNS server is not properly translating internet names, this can hinder your ability to use the software and/or access the website. Most ISPs typically resolve this issue within 3-5 hours. However, if the issue persists longer than this, you will need to raise the issue with your ISP.

• Click here if exception is "Java.net.SocketException:" (Connection Reset / Read Timed Out / Broken Pipe)

  This indicates that there may be a firewall on your computer and/or network that is preventing our software from accessing our servers. In such, our software requires sustained, direct and unrestricted outbound and inbound internet access by Java via port 80 and 443 to http://www.usmleworld.com

  If you are connecting via a home/private network, please ensure that you have access on these ports (including firewalls on your computer and the network). You may need to turn off or change settings on any internet security or firewall software on your computer, as many common firewalls (i.e. Norton, McAfee, PC-cilling, Windows Live OneCare, Webroot, ZoneAlarm, etc) block access on these ports by default.

  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 on these ports. In this instance, you will need to request that the network administrator make an exception for connections on ports 80 and 443 to http://www.usmleworld.com. If they are unable to make an exception for you, you will need to use your subscription from a non-public or home network.

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. Hence, you may be able to move from one question to 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.

There are two possible reasons for this issue:

• When 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
• 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 on these ports. In this instance, you will need to request that the network administrator make an exception for connections on ports 80 and 443 to http://www.usmleworld.com. If they are unable to make an exception for you, you will need to use your subscription from a non-public or home network.

If you do not wish to close Pop-up blocker program, you will have to press the keyboard control ('ctrl') key before clicking on any buttons. Release the control key when you get a new window that is open in full screen.

Our Step 2 CS videos are embedded within the software and require Adobe® Flash® Player, 8.0 or higher installed (available at http://www.adobe.com/products/flashplayer/). Once you have installed the latest version of Adobe® Flash® Player, restart your computer and access the Step 2 CS physical examination videos. On slower connection (dial-up or wireless) it may take a few seconds to buffer the clip for seamless playback and for that reason we recommend pausing the video as soon as it starts for a few seconds. That way when you press the play button a few seconds later the entire interaction will playback clearly without any interruptions.
