Hello, I'm an undergraduate math student planning on getting a Ph.D in math after I get my B.S. in pure math. I am wondering if a computer science minor really helps say, if you plan on going into Cryptography, or if it is more like what one teacher of mine put it, "if you have an advanced math degree and you say you can program, people will probably believe you." The reason why I'm wondering is that I've learned a lot of the material for the computer science minor offered at my school on my own but, I feel as if I wont have that much time to finish up the minor and study as hard as I want to for the G.R.E. math test as well as the various REUs I will be doing. Any thoughts?
