Can I increase my chances by taking (unneeded) extra classes?

<p>Hi,</p>

<p>I'm not really trying to raise my GPA by taking easy courses (although it is a side benefit) but there are some classes that I'd like to take even though I don't need it as a GE or Major.
I want to take a foreign language (not sure which), violin class, business course and maybe more. Even if I don't need those as a GE but I still pass them all with an A does it raise my chances of getting in a UC like UCI?</p>

<p>Thanks.</p>
