Great question. This designation will pop up if you are looking to create a new class, and you will need to choose one or the other. You will have access to the same study and editing features regardless of what you choose. If you ever want to switch your designation, just go into the About Tab for a class you own, and then switch to 'Instructor' or 'Student'.
This really just helps us better aid you in your study or teaching journey. Based on what you are doing in Braisncape, we can help guide you with Academy articles and other emails to provide you with the tools to be successful and use Brainscape in the most effective way. Depending on which of these designations you choose will help us properly guide you with the right information and emails.
Thanks so much and happy studying!
