Application error for UCs! Please Help!

I submitted my UC application close to the deadline day, Nov. 30th 2015, and have just now realized that I made an error. I was talking to my friends and remembered that I had chosen “PL” (planned) instead of “NO” for the second semester of one of my classes. I go to a Catholic school and the class in question is called Social Justice. Apparently it is only a one semester class. For the first semester I marked “In Progress (IP)” but for the second semester I marked it as a “planned course”. I was hoping somebody could give me some advice as to what I should do next. I already received confirmation emails from the colleges. I would appreciate some help or any information that you guys might have. Thanks!
