CEI Frequently Asked Questions

An access code is a password you use to access course content online. The content you access depends on the course, but can include things such as practice exam questions, interactive videos to help you understand course concepts, and course assignments. If your professor requires you to purchase an access code, it is because at least part of your grade will be related to and/or come from the online content. If your professor recommends that you purchase an access code, it is probably because the online content gives you access to additional study material.

No, access codes do not always include a subscription to an e-book.

Access codes are generally tied to specific textbooks, so you need to buy the access code that accompanies your specific textbook.

Unfortunately, you can't. Once an access code has been purchased it cannot be returned. To be certain, click the "Show Sample Access Code Voucher" and it will display all the terms and conditions set by the publisher of the access code.

Before buying your course materials, it is best to do a bit of research to determine the difference in cost between buying a new package that includes the access code versus buying a used package and access code separately. While we know you want to save money by buying used books, sometimes it ends up costing you more to buy the used book and access code separately. Also, if you purchase a used textbook from a source other than your University Bookstore, the access code may not be available for individual sale.

Access codes are supposed to be set up to allow students to gain access to online content for the duration of the course. Also, it can vary, depending on the code. Access generally lasts for a duration of between 6 months and 2 years. Click the "Show Sample Access Code Voucher" button to see all the details of any access code that you are considering.

Each access code includes details on how to get technical support from the publisher of the access code. We would recommend that you contact the publisher to see if there is a technical issue that is preventing you from using your access code.

Each access code is unique and can only be used by one person.

Some access codes are downloads; some have online access from any computer. Some codes allow you a choice of format; you will be asked when you register if you want a download or online access. In these cases, you cannot change your mind once you have made your choice. Be sure to check all the details of your access code before purchasing by clicking the "Show Sample Access Code Voucher" button.

Again, this varies by code. Most have limited print options.

No and yes. Most e-texts presently available are PDF versions of the hard copy text. However, they are linked digitally to study questions, quizzes, and rich media. For example, you may be reading a PDF on genetics and from that page, be able to click on an animated drawing, a dictionary of related terms, an in-depth concept sidebar and quiz questions.

Think of codes as short term rentals. You don't own it, so you can't sell it.
