I have a question and I feel very foolish. I thought I had registered for an admitted student day tomorrow, and have flown on a plane and bought a hotel room in a city about 6 hours from my home. Only now, I am unable to find any confirmation of my registration in my inbox, and I'm beginning to worry that I didn't press submit on the registration form, or it didn't go through. If for some reason I am not registered, will they still let me in? I've never been to one of these before so I wasn't sure what to expect.
