3 Years of the Same Language, or 4 Years total of two different Foreign Languages??

Hello, I am currently a sophomore in high school. We are registering for our Junior year classes now. I know that two years of foreign language is required while three is “recommended”. I am currently in Spanish 2 as a sophomore, but want to take Chinese 1 Junior year and Chinese 2 Senior year. (Our school previously has not offered Chinese, but will start teaching Chinese 1 next year). Is this any (dis)advantage? Because I am taking four years of foreign language, they are just not the same language… Surely this must be better than taking two years of Spanish alone. My reason for choosing Chinese is because it is much more useful and stands out more than Spanish. I really want to go to a UC or California school, and already 33% of California speaks Spanish, so I don’t think 3 years of Spanish is an advantage at all. Could I please get some thoughts ---- Spanish 1 & 2 followed by Chinese 1 & 2 or just Spanish 1, 2, 3 (and no foreign language senior year)? Thank you!! :)>-
