UC Riverside admission question

Hello everyone! I have this really important question and it has been keeping me up. If anyone could help me out I would be really grateful!
I got my admission into UCR! (yay!!) But on my application I had put that I was planning on taking Math 10 for my math requirement in the spring of 2015. I tried to get into this class at my community class but they were all filled. Is there anyway that they would deny my admission based on my inability to take one math course?

If you didn’t take the class you need to notify UCR. Any discrepancies between your self reported classes and your final transcript will be a problem.
