Which SAT Subject Tests to take?

<p>Hello!</p>

<p>I am a sophomore student; I am planning to take various SAT Subject Tests but I do not know what to take specifically. My goal is to become molecular virologist, so I am determing to take both SAT Biology E and SAT Biology M. If I am going to univerisity that focuses on the science & mathematics, do I have to take SAT World History and US History?</p>
