Double major or not

<p>Recently I am quite confused whether it is useful to get a double major in math and economics. I want to get a job in some bussiness field. I am now a math/economics major so is it really different if I am a math and Economics double major? and is it kind of probable for me to graduate in 4years if I choose to get a double major(I have got 5APs =28units)</p>

<p>just do the single math/econ major (through the math dept.)</p>

<p>any reason???</p>

<p>Not to hog your post but I was also wondering if you can graduate in 4 yrs if double major (say in Bizecon and Psychology)?</p>

<p>of course not ~as I am not interested in psychology</p>

<p>any help???</p>
