An access code is a series of numbers/letters 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 an access code, it is because at least part of your grade will be related to and/or come from the online content. For CMC, access codes are provide on your LMP Dashboard > Digital Bookshelf. You will reveal your code and navigate to a link, either provided by eCampus.com or your instructor, to redeem the code for access.
