My alma mater's undergrad physics curriculum required math through boundary value problems: basic calc, multivariate calc, vector calculus as a separate course with more in depth material, diff eq, partial differential equations/bvp. The whole math curriculum was about 6 semesters. Basically any physics major auto-qualified for a math cert/minor.
