could you rank these classes in terms of necessity to take if I intend to pursue a Ph.D in pure math? I don't know if I can fit everything, but I want to make sure I take the most important ones:
Ordinary Differential Equations
Geometries
Applied Regression Analysis
Chaotic Dynamics
Probability
Introduction to Statistical Inference
Set Theory
Elementary Theory of Numbers
Real Analysis I
Real Analysis II
Advanced Linear Algebra
Combinatorial Theory
Fourier Series and Boundary Value Problems
Abstract Algebra I
Abstract Algebra II
Differential Geometry
Functions of a Complex Variable
Topology
Applied Analysis
Thank you in advance~~
