I'm completing my BSc in pure mathematics soon and will continue to MSc in applied mathematics. My strengths are in linear algebra, algebra, and linear programming, but I have great skills in one-variable calculus and geometry, too. In my spare time, I have given some advice in mathematics especially to students in engineering or business studies.
