How much of a language do you need to know for a college to care?

<p>I’m already taking Spanish and took it 2 years in middle school and planning on taking it until Junior year so i’ll finish Spanish 4. I want to learn either Vietnamese or Japanese so how well do i need to know it before I can list it as “proficient” in my skills category? Also, I already know Mandarin and Cantonese so would that be considered as two languages? and can i say i’m fluent without taking the SAT 2 or AP test since i can’t read or write it?</p>
