Are Only Math and Science Subject Tests Required?

<p>I am a HS junior preparing to register for the June SAT Subject tests. I'm wondering whether I should take SAT US History, considering that I haven't begun studying and I am already going to take Math Level II and Chemistry.</p>

<p>Is US History or any other non-math/science tests ever required for admission? I've never seen it. The strangest requirement I've seen was the Carnegie Mellon SCS Molecular Biology requirement. Are there any gotchas I should be aware of? I'm currently interested in applying to CMU, Stevens University, Columbia, NYU, and Princeton, if that matters.</p>
