Question about applications & future classes...

<p>Hi there!</p>

<p>I'm a high school senior and almost two weeks ago, I submitted my UC apps along with a few private apps. In the section where you list the classes you'll be taking in your senior year, I included the classes that I thought I would be taking next semester. I'm concurrently enrolled in a community college, so I listed the classes I was planning to take there as well.
However, I do not have a very early registration slot, so when I could finally register for my college classes, almost all of the ones I had planned to take were full. </p>

<p>So my question is, since I had to register for different classes than the ones I had listed on my applications, do I have to inform the colleges I applied to about the changes? And if so, would I just be emailing the admissions office?</p>

<p>Thank you in advance!</p>
