Chance a Junior for UCs and CSUs + Looking for other schools to apply to

I decided to take Physics 2 because I didn’t know what other class to take and I had to take 6 classes. Will this be a big factor in my application?

I am currently registered for DE discrete math. Would that work? I am on the waitlist for multivariable calculus, so I’m not sure if I will be able to take it.
