I'm having the same problem. My course ID number is (617005) its dynamics, Kheirkhah. I receive this error, You are already registered for a different class section within this course. Please go to your class section URL to log in. I accidentally registered in the other dynamics wileyplus may i be switched the Kheirkhah's dynamics.
Yunhan & Dalton--the best way to resolve this would be to reach out to your previous Instructor and ask them to finish your previous class section. That will free you up to register in a new class section using the same book.
However, if you are unable to get a hold of your previous instructor, contact our support team through LIVE CHAT, and they should be able to move you to the proper class section.
