When should I arrive on campus?

Hi!

So I’m an out of state student from Illinois. Since I have to pay for my own ticket, I was wondering when I should arrive on campus for the Fall 2017 quarter. I’m sorry for asking this here it’s just that navigating the website is confusing. I know that the first day of classes is September 27th but there’s also Dawg Daze and stuff happening before classes. Also, my A&O day is in August so I’m hoping to buy my ticket before then.

Thanks in advance!
