WileyPLUS is an instructor driven resource. In order for you to purchase access to this title in WileyPLUS, your instructor would have to create a class section for you to log into. Once there, you would have access to the textbook and miscellaneous resources for students, including videos, and the like; however, no solutions for questions would be presented for students to access, unless they were already available in the textbook, i.e. answers that can be found in the back of the text.

I recommend accessing the Student Companion site as an alternative.
