advising and registration

Tomorrow is my advising/ registration date. FINALLY. Now, I'm confused. Do I have to do advising in order to register? Because I'm across the country, and no one has told me there's any advising thingy I need to plan to do. So, will the website let me register for classes if I don't go to advising? If it matters, I am not a freshman; I'm in the NSE program, a transfer.
