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.

In order to gain access to WebAssign, you must purchase an access code as detailed below.  If you purchased an access code in MATH 117 for the Stitz-Zeager 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: To get started, you will need a class key which your instructor will provide.  The class key begins with the letters luc and is followed by two four digit numbers.  So the class key will have the form: luc #### ####.  Once you have the class key, proceed according to the following steps:

1. Go to www.webassign.net and click on the Enter Class Key tab.
2. Enter the class key your instructor gave you and click Submit.
3. If the correct class and section is listed, click Yes, this is my class.
4. If you purchased an access code for the Stitz-Zeager text in a previous semester, you do not need to purchase another code.  Check I already have a WebAssign account and enter your username, institution, and password.  The institution is luc all in lowercase.  The account you enter here is the one you used after you originally purchased the access code.  You will not be asked to re-enter that access code.  Go to Step 7.
5. If you have not purchased an access code and if you do not already have a WebAssign account, check I need to create a WebAssign account and click Continue.  (If you created a WebAssign account in another Mathematics or Statistics course at Loyola, that account is still valid and can be used for this course.)  Otherwise, check I already have a WebAssign account and enter your username, institution, and password.  The institution is luc all in lowercase.
6. At this point, you will have three choices:
• Enter an access code purchased at the Loyola Bookstore or from the Acadiem website,
• You may be given the option to purchase an access code online from WebAssign.  If given this option DO NOT take it as the access code generated will not work; refunds for taking this option are not guaranteed, or
• Continue the 14 day free trial.

Select the appropriate choice to access the e-book and homework assignments.

• If at any time you run into technical difficulty using WebAssign, you can contact WebAssign directly by email or phone.  Go to https://webassign.com/support/student-support/ to address the difficulty and to find the days and times of available support.

• For Windows users:
• Mozilla Firefox (version 38 or later)
