Hello,
 
	I am a junior majoring in Mathematical Economics with a minor in Data Science at an average rank university. I am planning to apply to top 20 Master programs in Stat/Biostat. 
 
	Right now I am very unsure about whether I should switch to a B.A. in Pure Math, which I was told would be more competitive for top MS programs in Stat (and a career in Data Science?). 
 
	I like econ, but at the same time I think it is necessary to take more math classes. If I switch to pure math, I will be able to change 2 econ classes (Mathematical Economics, which covers basic convex analysis and optimization, and Econometrics 2) to two upper level math courses  
 
	Below are my courses history and intended plan if I stay as a Mathematical economics major.
 
	Courses Taken:
 
	         Math: Multivariate Calculus, Linear Algebra, Probability Theory, Discrete Math (Intro to proof), Real and Complex Analysis 1, Intro to Modern Algebra.
 
	         Other: Intermediate Micro, Intermediate Macro, Econometrics 1, Money and Banking, Biostatistics, Java 1, Java 2
 
	Intending to take:
 
				
					Fall Junior
				 
				
					Real & Complex Analysis 1
				 
				
					Econometrics 1 (Grad Course)
				 
				
					Money and Banking
				 
				
					Intro to Modern Algebra (Ring Theory)
				 
				
					Biostatistics
				 
				
					 
				 
			
			
				
					Spring Junior
				 
				
					Real & Complex Analysis 2
				 
				
					Theoretical Linear Algebra
				 
				
					Ordinary Differential Equations
				 
				
					Mathematical Statistics
				 
				
					Principles of Data Science
				 
			
		
				
					Fall Senior
				 
				
					Numerical Analysis 1
				 
				
					Honors Physics 1
				 
				
					Probability 2 (Stochastic Process)
				 
				
					Foundation of Machine Learning
				 
				
					Applied Math OR Complex Analysis OR Algebra (group theory)
				 
				
					 
				 
			
			
				
					Spring Senior
				 
				
					Mathematical Economics*
				 
				
					Partial Differential Equations
				 
				
					Data Intensive and Cloud Computing
				 
				
					Physics 2
				 
				
					Econometrics 2* (grad course)
				 
				
					Econ Writing Seminar
				 
			
		
	 
 
	As you can see, if I change to a pure math major, then I will be able to make changes as follow:
 
	                          Mathematical Economics (Convex optimization) -> 1 math elective in (Topology, Numerical Analysis 2, Number Theory)
 
	                          Econometrics 2 -> 1 elective in (Number theory, Nonparametric Statistics, or some other math elective)
 
	Do you guys think it would be worth it to make this change? Like i said, I like econ, but I also need to be practical, and to increase my admission chance to top MS programs, I think I will need more math. So I guess my real question is that would 2 more math electives instead quantitative econ classes be make much of a difference?
 
	 
 
	Thank you so much for your time!
