<p>2 years of mandarin doesn’t sound like all that much of a language in & of itself. For my S, he much preferred to have as solid a background in math & physics as possible before starting college engineering. He did repeat all the math & science when he started EE, but was very comfortable as nearly everyone else in his classes had also taken all the AP physics offered by their respective HSs.
There are many ways a student can show breadth, especially in college course selection & ECs.</p>
