I'm currently a junior at Duke University studying math, physics, and German. I've been competing in various math competitions and olympiads for many years and greatly enjoy helping other people learn. I've taken Multivariable Calculus, Linear Algebra, Non-Euclidean Geometry, Number Theory, Differential Equations, Probability, Real Analysis, the Putnam class (3 times), 2 semesters of Complex Analysis, 2 semesters of Abstract Algebra, Topology, 2 semesters of Differential Geometry, and Representation Theory, and I'm glad to share any of that knowledge with anyone who needs help :)
