Frequently Asked Questions

I have logged into WebAssign, but I am not seeing my course.

First, please make sure you are logging in at U of Illinois' WebAssign page: https://www.webassign.net/uiuc/login.html. Your course enrollment will NOT update if you are not logging in via this site. If you have changed sections or recently enrolled in the course, please note that it may take 24-48 hours for your enrollment to update in WebAssign. If you are still having issues, please email webassign@illinois.edu for assistance. Please include details on the course in which you should be enrolled.

I am having trouble with my access code.

If your access code begins with the prefix "Cengage-RMY" or "Cengage-RSY", please be sure you are including the full code prefix when entering your access code. For example, you would enter "Cengage-RSY ABCD 1234 EFGH 5678". If you are still encountering difficulty, please email webassign@illinois.edu. In your email, please include the code you are attempting to register.

I have already successfully purchased access/entered my access code, but I am seeing a trial countdown.

If you have already successfully purchased/registered access, you may still have access to a Cengage Unlimited trial. Cengage Unlimited is a subscription option that provides you access to your materials for this course as well as any other course using Cengage materials. If you have already purchased your WebAssign access, you may be able to upgrade to Cengage Unlimited for a reduced price (or upgrade for free after purchasing a multi-term code). If you do not wish to upgrade to Cengage Unlimited, you will NOT lose access to your purchased WebAssign course at the end of the trial period. It is only your Cengage Unlimited trial that will expire.
