Hello there, @ChristinaMarcia ...
The other school you are taking a class at should communicate with you on how to access your course within that Canvas environment. Generally speaking, each school will have their own Canvas environment, and that usually means that you'll have a separate login to that course compared to your login that you'd use at another school. I would highly recommend that you reach out to folks at your school in the Online Learning / eLearning / Distance Education department to get this figured out. Or, if you happen to know who the Canvas administrator is at your school, you could talk with that person, too. Sorry that we cannot be of more help, but we don't have access to your school's Canvas environment or any of your courses. We only have access to our own courses in our own Canvas environment. Good luck to you! Keep us posted!
