Math 207 How to Pay for WebAssign

You need to follow the steps below and pay for WebAssign within the first two weeks of the quarter.
First visit this link:Pay for Online Access here. Be very careful not to click the "Start My Free Trial" link or the "Subscribe Now" link at the top of the page. Its an attempt to trick you into buying Cengage Unlimited, which you definitely don't need. Scroll to the bottom of the page. You should see "WebAssign Homework Instant Access, Generic, 1st Edition". Click that link and complete the checkout process.
Now login to the WebAssign for UW website.
Now click on the link that says "My Cengage Home"
You should see the "Epin product"-- the screenshots below are for math124, but I expect you will see the analogous screens for math 207:
When you click on the "Epin product", you will see your "pincode"

Copy your pincode.
Now click on your Math 207 course link
Now click on "RegisterYourCode
Enter the code and click "Register"
And, hopefully, you're done. If you're still having trouble, call the help number 800.354.9706. Do not call Math Advising, they can't help you with WebAssign issues.
