WebAssign is an online homework system used by the Mathematics department for several courses including Calculus.

Beginning Fall 2018 the login prcedure has changed slightly.  You still need to first log in with your identikey at https://www.webassign.net/colorado/login.html.  Then if you have not already done so, you will be asked to sign in with a Cengage account.  If you already have a Cengage account that was used for another course you can use that here.  Otherwise create a new account with your CU email address.  After that you should see your class(es).

Remember that if you are waitlisted, you can still have an account in WebAssign and are responsible for keeping up with class assignments.  You cannot get an extension for assignments that were missed for failure to follow these instructions!

Please browse the FAQs below for answers to common problems.  If you are still having trouble you can send an email to math-help@colorado.edu.
Emails should include your first and last name, Identikey user name, student ID number, what MATH course you are in, and the class section number.  Emails should be answered within 24 hours.

I cannot sign in to WebAssign or see my classes

My user name or email address is not recognized

For MATH classes please make sure you are signing in at the CU login page (as seen below): https://www.webassign.net/colorado/login.html

Your username is usually four letters and four numbers, but will be the same ID you use to log in to the myCUinfo page.  Do not enter an email address here, it will not be recognized.

Your password is your identikey password.  Again it is the same information you enter to sign in to the myCUinfo page.  If you are uncertain what it is, you can reset your password here.


CU login page

I can sign in to the CU login page, but I have no classes listed

We will need to create an account for you.  Please use the email link above to request an account.

I transferred from APPM into a MATH class

If you have transferred from an APPM class into MATH, we will need to create a new account for you in the MATH class.  Please use the email link above and include all of the requested information.

If you already purchased an access code while in the APPM class, please let us know which course and section number when you send an email, and we will have your access code transferred to your new MATH class.

If you wish to be removed from your APPM class in WebAssign, you will need to email the instructor of the APPM class to let them know you have transferred out of their class and wish to be removed.

I am trying to create an account and need the Class Key

STOP!  You are in the wrong location, MATH classes do not use class keys and you cannot create your own account.  Please make sure you are signing in to the CU login page with your Identikey credentials to access MATH classes: https://www.webassign.net/colorado/login.html

If your user name is not recognized or you sign in and still have no classes listed, please see the FAQs above for more information.

I am having problems with my class after signing in

When I log in, I am listed in the wrong course or section number

WebAssign is not aware when you change classes, and the initial accounts are created based on what classes you were signed up for or waitlisted in on the Friday before classes start.

To transfer to a different class in WebAssign, please use the email link above, and also let us know the course and section number WebAssign currently lists you in (so we can remove that account) and the course and section number you SHOULD be listed in (so a new account can be created, or if you are in the same course then your existing account and any completed assignments will be transferred to the correct section).

My trial period has ended and I can no longer see my assignments

You will need to purchase an Access code for WebAssign.  You can purchase packages with the course book from the CU Bookstore, or directly from Cengage after you sign in to WebAssign.

What are the differences between the types of access codes?

There are several different options available when purchasing an access code.  The first thing to consider is what type of book you wish to get with your purchase.  An eBook will allow you to view the book online through a laptop or mobile device.  There is a looseleaf version which is the printed pages punched for a 3-ring binder.  You may also purchase a hardcover book.

Next you want to consider how many classes you are making your purchase for.  If you are taking other course such as Psychology which also use Cengage online materials, you may wish to purchase 'Cengage Ultimate' which is a single access code that gains access to ALL of your classes for that semester (note the differences with Calculus below).  If you are only taking a one-term class that uses Cengage/WebAssign, such as Pre-Calculus (MATH1150), you may wish to purchase a single-semester access code.

The Claculus class (MATH1300, MATH2300, and MATH2400) is slightly different than others.  Because these classes use the same book and are typically taken together, both Cengage Ultimate and a single-term access code will actually work through each semester of all three classes.

If you have any questions about which access code package is right for you, feel free to email the address above.

My access code is not accepted when I enter it

A common mistake is not entering the entire access code, exactly as it appears on the card.  You must include the spaces and dashes as shown.  Also include the beginning portion -- for example if your code starts with "Cengage-RSY" then you must also include that portion.

If you purchased your access code online through the CU bookstore, you may actually have a RedShelf code on your receipt.  Please note the directions included with your purchase and enter that code on the RedShelf website to obtain your WebAssign access code.

If you need further help please send an email to the link above, and try to include a large screenshot of the WebAssign page rejecting your access code, along with the access code you are trying to enter.

I have completed a few assignments in WebAssign, but my grade does not show on myCUinfo

The grades from WebAssign have to be transferred by your instructor before you will see them on myCUinfo.  This may only happen around midterms and final exams, or it may happen more frequently, however if your score is registered in WebAssign then it will be transferred by the end of the semester.

My instructor has transferred scores from WebAssign, but I still have a zero

Student accounts are created automatically just before classes start at the beginning of the semester, and often times students are signed up or waitlisted for mutiple sections.  When you log in to WebAssign take a look to see what section number it has you listed in.  If this information is not correct please use the email link above and include what course and section number WebAssign shows you are in, and what course and section you SHOULD be in.  Your account and completed assignments will be transferred to the correct class and become available for your instructor to transfer to myCUinfo.

I transferred from APPM into MATH

If you have transferred from an APPM class into MATH, we will need to create a new account for you in the MATH class.  Please use the email link above and include all of the requested information.

If you already purchased an access code while in the APPM class, please let us know which course and section number when you send an email, and we will have your access code transferred to your new MATH class.

If you wish to be removed from your APPM class in WebAssign, you will need to email the instructor of the APPM class to let them know you have transferred out of their class and wish to be removed.

I do not have any assignments listed

Other questions about WebAssign

Can I get an extension on assignments?

If you are waitlisted for a class at the beginning of the semester you can still obtain a WebAssign account and are responsible for keeping up with assignments.  You cannot get an extension for missed assignments if you have failed to follow these instructions.

Extensions may be given for medical or other emergencies, but check with your class instructor for approval.  If approval is given, ask your instructor to email math-help@colorado.edu and let us know what course and section number, which assignments to provide the extension for, and what date to extend them to.

How can I see my old assignments?

WebAssign only shows assignments from the previous two weeks by default, however it is possible to see all of the assignments from your class.  At the top of your assignment list will be a bar (as below) showing the number of past and current assignments.  If you click where it says "All" then you will be shown a list of all assignments beginning at the start of the semester.
