Should I take Chinese or Spanish in high school?

I am Chinese and I know how to speak it but not so much reading and writing. I have completed Spanish 1 and would be starting in Spanish 2. Please help!! I need to decide very soon!

What level in Chinese would you start at?
What is the highest level available in each?

What type of college are you aiming for?

I think you should continue to 4 yrs of Spanish, learning to speak your own native language isn’t terribly impressive if you are aimed at selective schools. Can’t you self study for Chinese AP?
