Students in some physics courses such as PHYS 172/172H/272/272H need to have an account on WebAssign and to start using it for homework assignments beginning on the first day of class. If you bought a new textbook, it should have come bundled with a coupon for a free WebAssign account. Otherwise you need to go to the WebAssign home page and purchase an account on-line (http://www.webassign.net/).
The WebAssign log-in URL for Purdue Physics courses is http://www.webassign.net/purdue/login.html . Please do NOT use the log-in boxes on the WebAssign home page in the previous paragraph or those that were used up to the last semester; they will no longer work for you. Your WebAssign log-in credentials are identical to your Purdue career account. Use your career account user id and password to log in to WebAssign.
Once you log in, go to "My Options" and update your contact information, especially your email address so that we can send you important information. Then go to "Guide" to learn about using WebAssign.
