WebAssign from Cengage Student Access Code

Student Access Code for WebAssign by Cengage My professor messed up and half my class purchased the wrong access code, and I could not get a refund at my schools bookstore. I paid $90 for this so I would love to resell it to someone who needs it. I already checked with the company, this code is UNUSED! Please check the ISBN number and even possibly go to their student support AND your professor to make sure this is the right code for your course ISBN 10: 1-928550-20-7 EAN 13: 978-1-928550-20-4
