I am going to be a rising junior (undergrad), and I plan on applying to graduate school in mathematics. Our school offers the opportunity to get a B.S./M.S. in math, or simply a math B.S. To get a B.S./M.S., I'd have to sacrifice some courses outside of math (like english, history, etc.) in order to take more graduate math classes (need 8 total). I'd still plan on taking graduate courses even with the B.S., but it would probably be around 5-7 instead of the 8 needed.
In terms of graduate school admissions, would this matter at all? It seems to me that there's probably not too much of a difference given that they would see the coursework anyways. But who knows, maybe given the fact that there's so little time spent on each application, that having a M.S. would be just enough to stand out and have a name remembered.
EDIT: United States - sorry about that!
