<p>I know that CS and math have a lot of overlapping courses in lower-division courses, and upper-division requirements need only a few extra classes, but how difficult is it to balance a math minor alongside a CS major? How much harder is it to double-major in CS and math than it is to major in CS and minor in math?</p>
<p>I don't think the math major is substantially harder than the math minor--for pure math, it's 4 more courses and for applied math, it's 3 more courses. Upper-div CS can actually be used to fulfill these requirements (though I think only 2 such courses of your choice will work for pure math).</p>
<p>you are allowed a two ud overlap for double majors. No more than two upperdivision courses can be used for both majors</p>
