<p>So basically I’m currently a high school student, and I’ve been consistently scoring As and A*s in sciences, but also in most social science/humanity subjects, so people have been constantly telling me that it would be a good idea to do a science major like chemistry or physics then go on to do Economics or Business in a business school or something for a Ph.D, and I was wondering what’s a good science major that provides me with plenty of knowledge and opportunities? And yes, I am willing to do 8 years of study so no questions about that. But generally, I prefer more ‘practical’ sciences like Marine Biology than theoretical ones, but I’m not sure if Marine Biology is a very good major unless I’m planning on pursuing a career related to that :\ Thanks!</p>
<p>The best route to an economics PHD is a math major. A close second is computer science. Since you like practical, you should try for an applied mathematics major in something like statistics or just general applied math. Graduate level economics is actually considered a subfield of applied math. Also, if you change your mind about being a PHd in economics, a math degree prepares you well for an insanely large number of professional career paths.</p>
<p>Majoring in something like biology or chemistry as preparation for an economics graduate degree makes very little sense, so I don’t know who gave you this idea, but whoever they are make sure to quit listening to them.</p>
<p>A math major with courses or minors in economics (the math-heavy courses) and statistics will be a strong preparation for graduate school in economics, as well as good preparation for employment in things like actuarial or quantitative finance jobs. Other major / minor combinations of these subjects can also be good for the same purposes.</p>

<p>Biology and chemistry tend to have poor job and career prospects at the bachelor’s level, and biology majors usually do not take enough math to be strong candidates for graduate school in economics.</p>
