Cognella Active Learning provides you with interactive learning activities, such as flashcards, quizzes, PowerPoint lectures, etc., while an ebook provides you with reading material only. A Cognella Active Learning environment will not contain the same information as a print or digital textbook assigned for your course unless the description in the Cognella store specifically says that it includes the ebook. If your instructor has assigned Cognella Active Learning and a textbook, you must purchase both components for your course. Often, these components are provided as a bundle at a discount. If your instructor has assigned Cognella Active Learning and a textbook, the Active course will be free with purchase of the textbook from our website or as a new copy from your campus bookstore. If you purchase the textbook from a third-party, you will need to purchase access to Active Learning from our website.
