I've found classes in graph theory, linear algebra, probability, and statistics to be the most useful for me. Probability and statistics have much more practical applications outside the classroom.

I received a minor in math, and it's been more practical than my major (information systems). It helps you frame and understand the world differently.

Classes get much tougher once you start doing math with letters instead of numbers (usually linear algebra and up), because things transition from computation to understanding the properties of numbers.
