Before you purchase, check with your instructor or review your course syllabus to ensure that you select the correct ISBN. Several versions of Pearsons MyLab & Mastering products exist for each title, including customized versions for individual schools, and registrations are not transferable. In addition, you may need a CourseID, provided by your instructor, to register for and use Pearsons MyLab & Mastering products.
Access codes for Pearsons MyLab & Mastering products may not be included when purchasing or renting from companies other than Pearson; check with the seller before completing your purchase.
Used or rental books:
If you rent or purchase a used book with an access code, the access code may have been redeemed previously and you may have to purchase a new access code.
Access codes that are purchased from sellers other than Pearson carry a higher risk of being either the wrong ISBN or a previously redeemed code. Check with the seller prior to purchase.
