WebAssign is an online, interactive environment for teaching and learning. Using WebAssign students will complete Core Homework Problems common to all sections; individual instructors may also assign additional homework. WebAssign also provides access to the text as an e-book. By department policy, homework will count at least 5% towards students' final course grade. The ground rules provided by your instructor will have further details.

You may begin using WebAssign on the first day of class. In order to access WebAssign after the 14-day grace period, you must purchase an access code as detailed below. If you purchased an access code in STAT 103 for the Brase–Brase text in a previous semester, do not purchase a new code as the code you previously purchased remains valid.

Instructions for students to obtain the e-book and to use WebAssign: Once your instructor has uploaded the class roster to WebAssign, your personal class page will be activated. You will access it with your Loyola ID and password as detailed below. (Note to returning students: there is a change from previous semesters... you no longer need a class key to use WebAssign.)

  1. Go to www.webassign.net/luc/login.html (Note the change in URL from previous semesters.)
  2. Use the LOG IN @ LOYOLA UNIVERSITY CHICAGO button in the center of the page. The LOG IN button in the upper right-hand corner should NOT be used.
  3. Selecting the Loyola login button will bring you to a standard Loyola login page, where you will enter your Loyola ID and password.
  4. Successful login should bring you to a WebAssign home screen from which you can access any of your courses having a WebAssign component.
  5. Select the desired course. If you have not already registered an access code for the course, a notice will be displayed with three choices:
    • Enter an access code (purchased at the Loyola Bookstore or from the Cengage website),
    • Purchase an access code (online from WebAssign), or
    • Continue the free trial.
    Select the appropriate choice to access the e-book and homework assignments.
  6. If you purchased an access code for the Brase–Brase text in a previous semester, you do not need to purchase another code. 
  7. If at any time you run into technical difficulty using WebAssign, you can contact WebAssign directly by email or phone.  Visit https://webassign.com/support/student-support/ to get started.

Software requirements for WebAssign: You must have the most recent versions of Flash Player (version 10 or later) and Java loaded on your computer for WebAssign to work properly.  The most recent version of Flash can be downloaded from www.adobe.com/products/flashplayer and the most recent version of Java can be downloaded from http://java.com.  The following browsers are supported by WebAssign:

  • For Windows users:
    • Mozilla Firefox (version 38 or later)
    • Internet Explorer/Microsoft Edge (version 11 or later)
    • Google Chrome (version 44 or later)
  • For Mac users:
    • Mozilla Firefox (version 38 or later)
    • Google Chrome (version 44 or later)
    • Apple Safari (version 8 or later)
  • For iPad users (iOS 8 or later):
  • Apple Safari (version 8 or later)

As you work WebAssign problems, WebAssign will warn you if you need additional plug-ins.  If you run into issues with system requirements, go to http://www.webassign.net/manual/instructor_guide/c_a_system_requirements.htm or contact WebAssign technical support at https://webassign.com/support/student-support/.
