You need user ID password to access protected area (i.e., lecture slides, assignments, etc.) of this web site. To grant you access, we need to verify that you are a USC student (although you do not have to be registered for the course at this time). Please note this has nothing to do with gaining access to the class Piazza Forum.
What To Do
Registration is either unavailable or closed at this time. (You will not see a submit button in this case.) It will be open soon after the semester starts and it will be closed after the class roster become fixed.
