Missed orientation?

I decided not to go to orientation earlier this summer because of how much it costed, and I was just going to attend the webinar/ online advising sessions that happened a few days ago. However, I screwed up and completely forgot about it until today. I’m freaking out right now because now I feel completely clueless. Does anyone know if there’s another orientation alternative? I also read somewhere they have Fall orientation on September 20th; is that a substitute for summer orientation for those who couldn’t make it to the summer sessions?
Thanks!
