<p>I wrote in my essay that I wanted to study Math&Physics double major and got accepted by CAS. But then I changed my mind and want to study Math&Eco, yet my I-20 says my Primary Major is Physics,General. What do I do?</p>
<p>BTW, how hard is mathematics and economics? In terms of workload?</p>
<ol>
<li>nothing</li>
<li>pretty hard, from what i've heard. but do what you love.</li>
</ol>
<p>My advice would be to concentrate on the math major, and explore both the physics and econ options, which are easy to do within the scope of the math major.</p>
<p>Generally speaking, a math/physics major may often be considered more employable than math/econ, simply because they are hardcore.</p>
<p>Econ/math is really popular among econ majors. The econ major consists of only 8 classes and it's extremely flexible. I'm an econ major and I'm able to fit in another major and a concentration without too much effort. </p>
<p>And while I don't know about math/physics, the math/econ majors I know didn't have any problems finding jobs after graduation. Though it depends on what you want to do- they are mostly ibankers.</p>
