Thank you for your post!
WileyPLUS codes are not semester-specific and your account will be able to continue accessing any new class sections within a course as long as the textbook/edition remains the same. I see that you're not currently enrolled in any active class sections.
Your instructor should have provided you with a student flyer, or a class section ID, where you can go to access the new section. Navigate to that class and log in with your existing account. As long as the new class section uses one of the below titles, you will be granted immediate access. If the edition has changed, please let me know:
Kieso, Intermediate Accounting, 16e
202/223: Financial Accounting, WileyPLUS Custom Course for Montana State University – Bozeman
Please let me know if you have any questions. Have a great day!
