<p>A few things. Unless you’re going into research, I would choose applied math over pure because it gives you more options career wise. If I were in your situation, I would pursue a double major with one minor, or one major with a triple minor. Keep in mind that this will take <em>extremely</em> hard work and you’ll hardly have time for extracurricular activities or a life outside of academics period. If that doesn’t interest you, I would recommend checking out the “natural sciences” major.</p>
