In the box under "Enter Access Code", type your prefix (either "Cengage-RSY" or "Cengage-RMY") followed by your 16-character access code and click "Redeem".

If you get an error message such as The entered access code is not valid for your class, please ensure that you have typed the prefix exactly as it appears in your access code, including the word "Cengage" and the hyphen. If this does not seem to be the issue, please contact technical support at WebAssign for assistance.
