Sorry, student ALIBAMBA SILLAH.
Your status in Class 272.A01.Fall 2017.Lahijani is currently inactive - class isn't accessible to you.
I'm sorry about that, Alibamba--please, reach out to your WileyPLUS Instructor. They can go into their Class Section Information, and re-activate your account. It seems that it was inactivated by someone there at your school.
Tom with Wiley
