Hello, I am double majoring in physics and pure mathematics and was wondering which math courses to choose in my mathematical concentration. This is what I have to choose from: Three of the following courses: Math 407 Abstract Algebra (3) Math 412 Complex Analysis (3) Math 425 Differential Geometry (3) Math 430 Number Theory (3) Math 471 Combinatorics (3) and as it states, I only need to choose 3. Which of these would be best suited to take if I wanted to go into graduate school. Oh, and I already took Complex Analysis, so I guess that's counted out. Thanks!
