Dropping classes

I just applied to transfer and was currently taking a class required for UC Irvine, but since I did not get in and got into UC Riverside, I wanted to drop it since it’s not required for UCR but I’m not sure if thats allowed since I posted it as one of my in progress classes on my application. If I drop this class I would be able to put all my effort into my calculus class which is required by UCR, so I feel like that is what’s best in my situation, but I’m not sure if UCR will still make me take it. I’m going to email and call to let them know that I wanted to drop it but I was wondering if anyone has gone through this situation as well?

Email UCR and ask. Generally, it is not an issue.
