Foreign language requirement?!?!?!

<p>In the application guide I got from Princeton, it says that it is "encouraged" to take the SAT Subject Test in Spanish. However, their use of the word "requirement" confuses. I've been taking Spanish for 4 years and I am currently taking AP Spanish. I also intend to take the AP Spanish test.</p>

<p>Whats going on?!!?!!?</p>
