Above is the error message I am receiving when I'm trying to get into my new course. I am currently registered for physics 1 but need to be registered for physics 2 with access code 535163.
Thank you for your post!
I see that you're now enrolled in the correct class section.
Please let me know if there's anything else you need. Have a great day!
