This problem almost always occurs when files are downloaded to a mobile phone.

Our downloads are not designed for mobile phones. Phone operating systems often misplace the files or prevent them from being properly opened or unzipped, which leads to errors and confusion.

Solution: Submit a customer service request and we will reset your access. After that, download your files using: (1) A desktop or laptop computer, (2) A tablet with full file management capability.

Once customers switch to a desktop or tablet, the issue is typically resolved.

We've created a separate page for questions you might have about filling out the payment fields and other misleading info that doesn't apply to our products.  Tap/click the button below to view the help page.

Our checkout is processed by Payhip, an international payment platform used by digital sellers worldwide. As a result, the credit card form may behave differently than most US-based checkout systems.

You may notice: the credit card number fields shift or auto-format on the same line.  Your zip code may be requested more than once.

This is normal Payhip behavior and is typically related to how they support both digital and physical product sellers, where billing and shipping addresses may differ.

Important: These fields are required by the payment processor and do not indicate a problem with your order.

If the payment form continues to reject your details, carefully re-enter the information exactly as it appears on your card or contact your card issuer to confirm the billing ZIP code on file.

No.  We do not sell printed books or physical study materials. Book references shown on our site are provided for your convenience only and link to external sources where they can be purchased, downloaded, or viewed.

Yes.  We provide structured support for outdated files and refund requests when they are supported by verifiable evidence.

Because these situations depend on specific circumstances, full details and requirements are explained here: Refund Policy Page

Please review that page before submitting a request so you understand what qualifies and what documentation is required.

In rare cases, a customer may unintentionally place more than one order for the same product.  If you believe this has happened, contact customer service with your order details so we can review and resolve the situation.

You will receive one order confirmation email that contains both your purchase receipt and your download link.

Before contacting support, check: - Spam or Junk folder - Promotions or Updates tabs (Gmail) - Deleted or archived messages - Search your email for your order details or the company name.

If you still cannot locate the email, contact customer service and include your name and approximate purchase date so the link can be resent.

No. There is no advantage to waiting.

Exam content, requirements, and reference materials can change at any time. Ordering sooner gives you more time to review, study, and become familiar with the material before sitting for your exam.

Delaying your purchase often results in less preparation time and unnecessary stress.

No.  We do not sell, reproduce, or provide actual exam questions.  Doing so would be illegal and a violation of testing authority policies.

All questions in our study guides are original practice questions created specifically for exam preparation. They are designed to help you understand the material and improve readiness, not to duplicate live test content.

Testing location policies vary.

Some PSI and other testing authorities allow candidates to bring copyrighted bound reference materials into the exam room, provided there are no handwritten notes, highlights, or markings in the margins.&ndsp; Other locations may prohibit all outside materials.

You are responsible for confirming the specific rules of your testing center before your exam date.&ndsp; We recommend reviewing the official exam bulletin or contacting your testing provider directly for clarification.

Memorizing the questions alone does not guarantee you will pass.

Most exams require you to understand the material and apply it to different situations, not just remember specific answers. Our study guides are most effective when used to learn the concepts, recognize patterns, and strengthen problem-solving skills.

Use the questions to identify what you need to study further, not just to commit answers to memory.

Please contact us immediately using our “Contact” page to let us know there is a problem.  Be prepared to give a detailed description of each question that you think might be wrong.

It is important to check over your study materials for accuracy as soon as you receive them.  Material content can become out-of-date in a matter of a few months.  Licensing agencies and legal requirements dictate when information changes, which requires us to update our study materials regularly.  Additionally, some questions may have been removed from your materials and purged from our database.

Please read our “purchase guarantee page” about policies that might effect old files.

Book links are provided solely as a convenience so customers can easily locate referenced materials. You are not required to purchase from Amazon, and many of these books can be found elsewhere, including as lower-cost used editions.

We are not an Amazon affiliate and do not receive commissions or compensation from these links. Because of this, we cannot offer Amazon-based discounts or price incentives.

You are free to purchase the same titles from any retailer or source you prefer.

No.  We do not offer live training, video-based courses, or interactive online classes.  All products are self-study materials provided as downloadable study guides.

Customers use these materials independently to prepare at their own pace.

Customer support is handled exclusively through email.  This allows all requests to be documented, reviewed accurately, and responded to with clear, consistent information.

Email also ensures that technical questions, order details, and reference issues are handled correctly without misunderstanding or lost information.

All support requests are answered as they are received.
