If you are registering using your class group code there is no option for a student to accidentally register as an instructor. You can only register as an instructor by filling out a request for instructor access that is very clearly labelled. If you as a student have registered as an instructor, your login will be suspended prior to it being verified. What this means is that you will no longer be able to use that email address to later register as a student, and you will also not receive any access to instructors resources - note that registering for instructor access by itself does not give any access to resources, it is only after we verify you are an instructor that we provide access.
Students who register as instructors will need to register as students using their group code using a separate email address.
