Taking extra CC courses to improve GPA for grad school?

<p>I'll be attending UCI this fall, however I am wondering if it would be advisable for me to attempt taking extra CC courses in order to boost my GPA for grad school apps in the future (since they consider all schools of undergrad attendance). I expect to transfer from my current CC to UCI with a 3.82. Are there any restrictions on courses I may take, such as being CSU/UC transferable, or may I take just about any class within the CC for a grade? I'd like to take a few classes out of personal interest and perhaps some extracurriculars, without compromising my UC GPA in the process.</p>
