<p>First of all, the best math programs aren’t all at Ivy Leagues. #1 is MIT. In the top 20 are also Stanford, Berkeley, Chicago, Caltech, UCLA, Michigan, NYU, Brown, Texas-Austin, Northwestern, Wisconsin-Madison, Minnesota, Rutgers, UCSD, UIUC, and UMD-College Park. So look outside the Ivy Leagues for math.</p>
<p>Second of all, you have better chances if you are looking at applied mathematics. Pure mathematics programs are extremely competitive and probably won’t look very favorably upon candidates who don’t have a math major, UNLESS they have the equivalent of a math major taken in courses after college OR unless that major was very heavily related to math (computer science for example). That’s usually about 10 courses, at least. Pure math isn’t the kind of field you can just walk into with a few post-college classes. Pure math would also require some research experience, as well, and some experience doing proofs or theory.</p>
<p>However, applied math is an entirely different story. There are many applied math programs that are tailored towards people who don’t have extensive math backgrounds, especially if you are interested primarily in an MS program. Usually they’ll require you to have take multivariable calculus and linear algebra, and perhaps a few other classes.</p>
<p>Depending on your needs, you may not need to go to a top 20 or Ivy League program, though. Math is in high demand right now and math MS holders can pretty easily find jobs as long as the program is reputable. You should explore inexpensive options for the degree, as well. For example, there is a public program in my home state in the top 25 (SUNY Stony Brook) as well as one in the top 40 (CUNY).</p>
<p>With a major in health sciences, you may also be interested in biostatistics programs.</p>
