Forgot Class Schedule on Applications

I just realized that I submitted my common app without listing any of the classes I’d be taking second semester of my senior year. I listed my first semester classes, three of which are full year classes, but none of the electives I’ll be taking second semester. Is this something I need to email admissions about? Will colleges know what classes I’m taking when my counselor submits reports? What do I need to do to rectify this?

Just send an email to admissions. They are used to getting corrections and updates. Not a big deal.
