Several posters have already addressed what College courses would be good options.
Regarding the UC A-G course requirements, below is a list of the minimum courses required for UC admission. To be a competitive applicants, students take well above the minimums but College courses are not a requirement unless you exhaust your HS course offerings and have a specific interest in a subject and want to take more classes related to that subject. College courses can also fulfill the A-G course requirements if certain classes are not available at your HS.
A common A-G course requirement which is overlooked by many applicants is the year of a Visual/Performing arts course which can be easily fulfilled with a 1 semester College course.
Also asking what is COD Music? This may or may not fulfill the VPA requirement.
