Problem set grades are heavily based on how well you defend your answer by providing a coherent rationale.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
